当初、上記水素ガス供給装置１００は、前記本体部１１０の前記放出材容器１１２α，１１２βの内部に、水素ガス放出材１０２が収容されると共に水素ガス１０１が上限圧力値Ｐｔ（例えば３ＭＰａ）まで充填され、前記本体部１１０の前記吸蔵材容器１１３α，１１３βの内部に、水素を吸蔵していない水素ガス吸蔵材１０３が収容され、前記操作弁１２１，１２２α，１２２βが閉鎖した状態となっている。 Initially, in the hydrogen gas supply device 100, the hydrogen gas release material 102 is housed inside the release material containers 112α and 112β of the main body 110, and the hydrogen gas 101 is filled up to the upper limit pressure value Pt (for example, 3 MPa). The hydrogen gas storage material 103 that does not store hydrogen is housed inside the storage material containers 113α and 113β of the main body 110, and the operation valves 121, 122α and 122β are closed.

そして、前記制御装置１３０は、作動が開始されると、前記放出材容器１１２α，１１２β内に充填されている水素ガス１０１を予め設定された規定流量Ｆｓ１で送出するように前記操作弁１２１を制御する（Ｓ１１１）。 Then, when the operation is started, the control device 130 controls the operation valve 121 so as to deliver the hydrogen gas 101 filled in the release material containers 112α and 112β at a preset specified flow rate Fs1. (S111).

このようにして前記放出材容器１１２α，１１２β内に充填された水素ガス１０１を送出して、当該放出材容器１１２α，１１２β内の水素ガス１０１の圧力Ｐｈ１が下限圧力値Ｐｂ（例えば０．６ＭＰａ）未満（Ｐｈ１＜Ｐｂ）になると（Ｓ１１２）、前記制御装置１３０は、前記圧力センサ１３１からの情報に基づいて、前記格納容器１１１の径方向内寄りに位置する前記放出材容器１１２α内の前記吸蔵材容器１１３αへ水素ガス１０１を予め設定された規定流量Ｆｓ２で供給するように前記操作弁１２２αを制御する（Ｓ１１３）。 In this way, the hydrogen gas 101 filled in the release material containers 112α and 112β is sent out, and the pressure Ph1 of the hydrogen gas 101 in the release material containers 112α and 112β is the lower limit pressure value Pb (for example, 0.6 MPa). When it becomes less than (Ph1 <Pb) (S112), the control device 130 receives the occlusion in the release material container 112α located inward in the radial direction of the storage container 111 based on the information from the pressure sensor 131. The operation valve 122α is controlled so as to supply the hydrogen gas 101 to the material container 113α at a preset specified flow rate Fs2 (S113).

前記吸蔵材容器１１３α内へ水素ガス１０１が供給されると、水素ガス吸蔵材１０３は、水素ガス１０１を吸蔵すると同時に発熱（約２５０〜３５０℃）し、当該吸蔵材容器１１３αを介して前記放出材容器１１２α内の水素ガス放出材１０２を加熱する。これにより、前記放出材容器１１２α内の水素ガス放出材１０２は、加熱分解（約１００〜３５０℃）して水素ガス１０１を発生する。 When the hydrogen gas 101 is supplied into the storage material container 113α, the hydrogen gas storage material 103 absorbs the hydrogen gas 101 and at the same time generates heat (about 250 to 350 ° C.), and releases the hydrogen gas 101 through the storage material container 113α. The hydrogen gas releasing material 102 in the material container 112α is heated. As a result, the hydrogen gas release material 102 in the release material container 112α undergoes thermal decomposition (about 100 to 350 ° C.) to generate hydrogen gas 101.

そして、前記制御装置１３０は、前記圧力センサ１３３αからの情報に基づいて、前記吸蔵材容器１１３α内の圧力Ｐｈ２が基準圧力値Ｐｓ（例えば０．１ＭＰａ）以下（Ｐｈ２≦Ｐｓ）であるか否か確認し（Ｓ１１４）、当該吸蔵材容器１１３α内の圧力Ｐｈ２が基準圧力値Ｐｓ以下であると、前記圧力センサ１３１からの情報に基づいて、前記放出材容器１１２α内の水素ガス１０１の圧力Ｐｈ１が上限圧力値Ｐｔと下限圧力値Ｐｂとの間となるように（Ｐｂ≦Ｐｈ１≦Ｐｔ）、前記操作弁１２１，１２２αを制御する（Ｓ１１５）。 Then, based on the information from the pressure sensor 133α, the control device 130 determines whether or not the pressure Ph2 in the storage material container 113α is equal to or less than the reference pressure value Ps (for example, 0.1 MPa) (Ph2 ≦ Ps). After confirming (S114), when the pressure Ph2 in the storage material container 113α is equal to or less than the reference pressure value Ps, the pressure Ph1 of the hydrogen gas 101 in the release material container 112α is based on the information from the pressure sensor 131. The operation valves 121 and 122α are controlled so as to be between the upper limit pressure value Pt and the lower limit pressure value Pb (Pb ≦ Ph1 ≦ Pt) (S115).

このように前記吸蔵材容器１１３α内への水素ガス１０１の送給を行っているときに、当該吸蔵材容器１１３α内の温度Ｔｈ１が上限温度値Ｔｔ（例えば２５０℃）を超えてしまうと（Ｔｔ＜Ｔｈ１）（Ｓ１１６）、前記制御装置１３０は、前記温度センサ１３２αからの情報に基づいて、当該吸蔵材容器１１３α内への水素ガス１０１の送給を停止するように前記操作弁１２２αを閉鎖制御する（Ｓ１１７）。 When the hydrogen gas 101 is being supplied into the storage material container 113α in this way, if the temperature Th1 in the storage material container 113α exceeds the upper limit temperature value Tt (for example, 250 ° C.) (Tt). <Th1) (S116), the control device 130 closes and controls the operation valve 122α so as to stop the supply of the hydrogen gas 101 into the storage material container 113α based on the information from the temperature sensor 132α. (S117).

そして、前記吸蔵材容器１１３α内の温度Ｔｈ１が下限温度値Ｔｂ（例えば１００℃）未満（Ｔｈ１＜Ｔｂ）になると（Ｓ１１８）、前記制御装置１３０は、前記温度センサ１３２αからの情報に基づいて、当該吸蔵材容器１１３α内への水素ガス１０１の送給を再開するように前記操作弁１２２αを制御し（Ｓ１１９）、前記ステップＳ１１４に戻る。 Then, when the temperature Th1 in the storage material container 113α becomes less than the lower limit temperature value Tb (for example, 100 ° C.) (Th1 <Tb) (S118), the control device 130 is based on the information from the temperature sensor 132α. The operation valve 122α is controlled (S119) so as to restart the supply of the hydrogen gas 101 into the storage material container 113α, and the process returns to step S114.

このような前記吸蔵材容器１１３α内への水素ガス１０１の送給により、当該吸蔵材容器１１３α内の水素ガス吸蔵材１０３が水素１０１を吸蔵可能な上限容量にまで達すると、当該吸蔵材容器１１３α内の圧力Ｐｈ２が次第に上昇して、基準圧力値Ｐｓ（例えば０．１ＭＰａ）を超えるようになるので（Ｐｓ＜Ｐｈ２）、前記制御装置１３０は、前記圧力センサ１３３αからの情報に基づいて、前記格納容器１１１の径方向外寄りに位置する前記放出材容器１１２β内の前記吸蔵材容器１１３βへ水素ガス１０１を予め設定された規定流量Ｆｓ２で供給するように前記操作弁１２２βを制御する（Ｓ１２３）。 When the hydrogen gas storage material 103 in the storage material container 113α reaches the upper limit capacity capable of storing hydrogen 101 by such feeding of the hydrogen gas 101 into the storage material container 113α, the storage material container 113α Since the pressure Ph2 in the gas gradually rises to exceed the reference pressure value Ps (for example, 0.1 MPa) (Ps <Ph2), the control device 130 is based on the information from the pressure sensor 133α. The operation valve 122β is controlled so that the hydrogen gas 101 is supplied to the storage material container 113β in the release material container 112β located on the outer side in the radial direction of the storage container 111 at a predetermined predetermined flow rate Fs2 (S123). ..

前記吸蔵材容器１１３β内へ水素ガス１０１が供給されると、前記吸蔵材容器１１３αの場合と同様に、水素ガス吸蔵材１０３が、水素ガス１０１を吸蔵すると同時に発熱（約２５０〜３５０℃）し、当該吸蔵材容器１１３βを介して前記放出材容器１１２β内の水素ガス放出材１０２を加熱する。これにより、前記放出材容器１１２αの場合と同様に、前記放出材容器１１２β内の水素ガス放出材１０２は、加熱分解（約１００〜３５０℃）して水素ガス１０１を発生する。 When the hydrogen gas 101 is supplied into the storage material container 113β, the hydrogen gas storage material 103 generates heat (about 250 to 350 ° C.) at the same time as storing the hydrogen gas 101, as in the case of the storage material container 113α. The hydrogen gas release material 102 in the release material container 112β is heated via the storage material container 113β. As a result, the hydrogen gas release material 102 in the release material container 112β undergoes thermal decomposition (about 100 to 350 ° C.) to generate hydrogen gas 101, as in the case of the release material container 112α.

そして、前記制御装置１３０は、前記吸蔵材容器１１３αの場合と同様に、前記圧力センサ１３３βからの情報に基づいて、前記吸蔵材容器１１３β内の圧力Ｐｈ３が基準圧力値Ｐｓ（例えば０．１ＭＰａ）以下（Ｐｈ３≦Ｐｓ）であるか否か確認し（Ｓ１２４）、当該吸蔵材容器１１３β内の圧力Ｐｈ３が基準圧力値Ｐｓ以下であると、前記放出材容器１１２αの場合と同様に、前記圧力センサ１３１からの情報に基づいて、前記放出材容器１１２β内の水素ガス１０１の圧力Ｐｈ１が上限圧力値Ｐｔ（例えば３ＭＰａ）と下限圧力値Ｐｂ（例えば０．６ＭＰａ）との間となるように（Ｐｂ≦Ｐｈ１≦Ｐｔ）、前記操作弁１２１，１２２βを制御する（Ｓ１２５）。 Then, in the control device 130, the pressure Ph3 in the storage material container 113β is the reference pressure value Ps (for example, 0.1 MPa) based on the information from the pressure sensor 133β, as in the case of the storage material container 113α. It is confirmed whether or not it is the following (Ph3 ≦ Ps) (S124), and when the pressure Ph3 in the storage material container 113β is equal to or less than the reference pressure value Ps, the pressure sensor is the same as in the case of the release material container 112α. Based on the information from 131, the pressure Ph1 of the hydrogen gas 101 in the release material container 112β is set to be between the upper limit pressure value Pt (for example, 3 MPa) and the lower limit pressure value Pb (for example, 0.6 MPa) (Pb). ≤Ph1≤Pt) to control the operating valves 121 and 122β (S125).

このように前記吸蔵材容器１１３β内への水素ガス１０１の送給を行っているときに、当該吸蔵材容器１１３β内の温度Ｔｈ２が上限温度値Ｔｔ（例えば２５０℃）を超えてしまうと（Ｔｔ＜Ｔｈ２）（Ｓ１２６）、前記吸蔵材容器１１３αの場合と同様に、前記制御装置１３０は、前記温度センサ１３２βからの情報に基づいて、上記吸蔵材容器１１３β内への水素ガス１０１の送給を停止するように前記操作弁１２２βを閉鎖制御する（Ｓ１２７）。 When the hydrogen gas 101 is being supplied into the storage material container 113β in this way, if the temperature Th2 in the storage material container 113β exceeds the upper limit temperature value Tt (for example, 250 ° C.) (Tt). <Th2) (S126), as in the case of the storage material container 113α, the control device 130 supplies hydrogen gas 101 into the storage material container 113β based on the information from the temperature sensor 132β. The operation valve 122β is closed and controlled so as to stop (S127).

そして、前記吸蔵材容器１１３β内の温度Ｔｈ２が下限温度値Ｔｂ（例えば１００℃）未満（Ｔｈ２＜Ｔｂ）になると（Ｓ１２８）、前記吸蔵材容器１１３αの場合と同様に、前記制御装置１３０は、前記温度センサ１３２βからの情報に基づいて、上記吸蔵材容器１１３β内への水素ガス１０１の送給を再開するように前記操作弁１２２βを制御し（Ｓ１２９）、前記ステップＳ１２４に戻る。 Then, when the temperature Th2 in the storage material container 113β becomes less than the lower limit temperature value Tb (for example, 100 ° C.) (Th2 <Tb) (S128), the control device 130 receives the same as in the case of the storage material container 113α. Based on the information from the temperature sensor 132β, the operation valve 122β is controlled so as to restart the supply of the hydrogen gas 101 into the storage material container 113β (S129), and the process returns to the step S124.

このような前記吸蔵材容器１１３β内への水素ガス１０１の送給により、当該吸蔵材容器１１３β内の水素ガス吸蔵材１０３が水素１０１を吸蔵可能な上限容量にまで達すると、当該吸蔵材容器１１３β内の圧力Ｐｈ３が次第に上昇して、基準圧力値Ｐｓ（例えば０．１ＭＰａ）を超えるようになるので（Ｐｓ＜Ｐｈ３）、前記制御装置１３０は、前記圧力センサ１３３βからの情報に基づいて、運転を終了する。 When the hydrogen gas storage material 103 in the storage material container 113β reaches the upper limit capacity capable of storing hydrogen 101 by such feeding of the hydrogen gas 101 into the storage material container 113β, the storage material container 113β Since the internal pressure Ph3 gradually rises and exceeds the reference pressure value Ps (for example, 0.1 MPa) (Ps <Ph3), the control device 130 operates based on the information from the pressure sensor 133β. To finish.

つまり、本実施形態に係る水素ガス供給装置１００においては、放出材容器１１２β，１１２β内からの水素ガス１０１の一部を吸蔵材容器１１３α，１１３β内の水素ガス吸蔵材１０３に吸蔵させることにより熱を発生させ、この熱を利用して、放出材容器１１２α，１１２β内の水素ガス放出材１０２を加熱して水素ガス１０１を発生させるようにしたのである。 That is, in the hydrogen gas supply device 100 according to the present embodiment, heat is generated by storing a part of the hydrogen gas 101 from the release material containers 112β and 112β in the hydrogen gas storage material 103 in the storage material containers 113α and 113β. The hydrogen gas release material 102 in the release material containers 112α and 112β was heated by using this heat to generate the hydrogen gas 101.

このため、本実施形態に係る水素ガス供給装置１００において、水素ガス放出材１０２として、例えば、水素化金属である水素化アルミニウム（ＡｌＨ₃）を適用し、水素ガス吸蔵材１０３として、例えば、水素吸蔵合金である五酸化ニオブ（Ｎｂ₂Ｏ₅）添加マグネシウム（Ｍｇ）を適用すると、水素ガス吸蔵材１０３に吸蔵される水素ガス１０１の有する熱エネルギに対して１０倍以上となる熱エネルギを、水素ガス放出材１０２から放出される水素ガス１０１によって得ることができる。 Therefore, in the hydrogen gas supply device 100 according to the present embodiment, for example, aluminum hydride (AlH ₃ ), which is a metal hydride, is applied as the hydrogen gas release material 102, and as the hydrogen gas storage material 103, for example, hydrogen. _{When magnesium (Mg) added with niobium pentoxide (Nb 2} O ₅ ), which is a storage alloy, is applied, the heat energy that is 10 times or more that of the heat energy of the hydrogen gas 101 stored in the hydrogen gas storage material 103 is increased. It can be obtained by the hydrogen gas 101 released from the hydrogen gas release material 102.

したがって、本実施形態に係る水素ガス供給装置１００によれば、ポンプ等の動力源や電気ヒータ等の加熱源等のような消費電力の大きい補機を使用することなく、操作弁１２１，１２２α，１２２β等の消費電力の小さい補機だけで、必要十分な熱エネルギ量の水素ガス１０１を取り出して送給することができるので、二次電池の消費電力量を大きく抑制することができる。 Therefore, according to the hydrogen gas supply device 100 according to the present embodiment, the operating valves 121, 122α, without using an auxiliary machine having a large power consumption such as a power source such as a pump or a heating source such as an electric heater. Since the hydrogen gas 101 having a necessary and sufficient amount of heat energy can be taken out and supplied only by an auxiliary machine having a small power consumption such as 122β, the power consumption of the secondary battery can be greatly suppressed.

また、前記格納容器１１１の内部の径方向内寄りに前記放出材容器１１２αを配設すると共に、当該格納容器１１１の内部の径方向外寄りに前記放出材容器１１２βを配設することにより、まず、上記放出材容器１１２α内の前記吸蔵材容器１１３αに水素ガス１０１を供給して当該吸蔵材容器１１３α内の水素ガス吸蔵材１０３に吸蔵させて当該水素ガス吸蔵材１０３を発熱させ、当該水素ガス吸蔵材１０３の水素吸蔵上限容量に達してから、上記放出材容器１１２β内の前記吸蔵材容器１１３βに水素ガス１０１を供給して当該吸蔵材容器１１３β内の水素ガス吸蔵材１０３に吸蔵させて当該水素ガス吸蔵材１０３を発熱させるようにしたことから、上記放出材容器１１２αの内部から外部へ伝達する熱エネルギを利用して上記放出材容器１１２βを予熱することができるので、当該放出材容器１１２βを加熱する上記吸蔵材容器１１３β内の水素ガス吸蔵材１０３の量を減らすことができ、コストダウンを図ることができる。 Further, by arranging the release material container 112α inward in the radial direction inside the storage container 111 and arranging the release material container 112β inward in the radial direction inside the storage container 111, first, the release material container 112β is arranged. , The hydrogen gas 101 is supplied to the storage material container 113α in the release material container 112α and stored in the hydrogen gas storage material 103 in the storage material container 113α to generate heat of the hydrogen gas storage material 103, and the hydrogen gas is generated. After reaching the hydrogen storage upper limit capacity of the storage material 103, the hydrogen gas 101 is supplied to the storage material container 113β in the release material container 112β and stored in the hydrogen gas storage material 103 in the storage material container 113β. Since the hydrogen gas storage material 103 is made to generate heat, the release material container 112β can be preheated by utilizing the heat energy transmitted from the inside to the outside of the release material container 112α, so that the release material container 112β can be preheated. The amount of the hydrogen gas storage material 103 in the storage material container 113β for heating the gas storage material 103 can be reduced, and the cost can be reduced.

なお、前記水素ガス吸蔵材１０３としては、Ｍｇ₂Ｎｉ，ＺｒＭｎ₂，Ｎｂ₂Ｏ₅添加Ｍｇ等の水素吸蔵合金等を挙げることができ、前記水素ガス放出材１０２としては、水素化アルミニウム，水素化アルミリチウム，水素化アルミナトリウム（チタン触媒添加），活性マグネシウム（前記特許文献３（特に「実施例１，２」）に記載のもの），水素化ホウ素リチウム，水素化マグネシウム，水素化ホウ素ナトリウム等の水素化金属等の水素化物等や、Ｍｇ₂Ｎｉ，ＺｒＭｎ₂，Ｎｂ₂Ｏ₅添加Ｍｇ等の水素吸蔵合金等を挙げることができる。 Examples of the hydrogen gas storage material 103 include _{hydrogen storage alloys such as Mg 2} _{Ni, Zrmn 2} , and Nb ₂ O ₅ added Mg, and examples of the hydrogen gas release material 102 include aluminum hydride and hydrogen. Lithium hydride, sodium aluminum hydride (addition of titanium catalyst), active magnesium (described in Patent Document 3 (particularly, "Examples 1 and 2")), lithium boron hydride, magnesium hydride, sodium boron hydride. Examples thereof include hydrides such as hydrides such as Mg ₂ Ni, Zrmn ₂ , and hydrogen storage alloys such as Mg added with _{Nb 2} O _5.

このとき、前記水素ガス吸蔵材１０３においては、水素ガス１０１の吸蔵に伴う発熱温度が、前記水素ガス放出材１０２の水素ガス１０１の放出温度以上のものを選定、言い換えると、前記水素ガス放出材１０２においては、水素ガス１０１の放出温度が、前記水素ガス吸蔵材１０３の水素ガス１０１の吸蔵に伴う発熱温度以下のものを選定するようにする。 At this time, in the hydrogen gas storage material 103, one having a heat generation temperature associated with the storage of the hydrogen gas 101 equal to or higher than the discharge temperature of the hydrogen gas 101 of the hydrogen gas release material 102 is selected, in other words, the hydrogen gas release material. In 102, a hydrogen gas 101 having a discharge temperature equal to or lower than the heat generation temperature associated with the storage of the hydrogen gas 101 of the hydrogen gas storage material 103 is selected.

次に、上述した本実施形態に係る水素ガス供給装置２００の作動を図７Ａ〜７Ｄに基づいて説明する。 Next, the operation of the hydrogen gas supply device 200 according to the above-described embodiment will be described with reference to FIGS. 7A to 7D.

当初、上記水素ガス供給装置２００は、各前記本体部１１０Ａ，１１０Ｂの前記放出材容器１１２α，１１２βの内部に、水素ガス放出材１０２がそれぞれ収容されると共に水素ガス１０１が上限圧力値Ｐｔ（例えば３ＭＰａ）までそれぞれ充填され、各前記本体部１１０Ａ，１１０Ｂの前記吸蔵材容器１１３α，１１３βの内部に、水素を吸蔵していない水素ガス吸蔵材１０３がそれぞれ収容され、前記操作弁１２１Ａ，１２１Ｂ，１２２αＡ，１２２αＢ，１２２βＡ，１２２βＢ，２２３Ａ，２２３Ｂが閉鎖した状態となっている。 Initially, in the hydrogen gas supply device 200, the hydrogen gas release material 102 is housed inside the release material containers 112α and 112β of the main body 110A and 110B, respectively, and the hydrogen gas 101 has an upper limit pressure value Pt (for example). Hydrogen gas storage material 103 that does not store hydrogen is housed inside the storage material containers 113α and 113β of the main body 110A and 110B, respectively, and the operation valves 121A, 121B and 122αA are filled. , 122αB, 122βA, 122βB, 223A, 223B are in a closed state.

そして、前記制御装置２３０は、作動が開始されると、前述した実施形態の場合と同様に、前記本体部１１０Ａ内の前記放出材容器１１２α，１１２β内に充填されている水素ガス１０１を予め設定された規定流量Ｆｓ１で送出するように前記操作弁１２１Ａを制御する（Ｓ１１１）。 Then, when the operation of the control device 230 is started, the hydrogen gas 101 filled in the release material containers 112α and 112β in the main body 110A is preset in the same manner as in the case of the above-described embodiment. The operation valve 121A is controlled so as to be delivered at the specified specified flow rate Fs1 (S111).

このようにして前記本体部１１０Ａの前記放出材容器１１２α，１１２β内に充填された水素ガス１０１を送出して、当該本体部１１０Ａの当該放出材容器１１２α，１１２β内の水素ガス１０１の圧力Ｐｈ１が下限圧力値Ｐｂ（例えば０．６ＭＰａ）未満（Ｐｈ１＜Ｐｂ）になると（Ｓ１１２）、前記制御装置２３０は、前記圧力センサ１３１Ａからの情報に基づいて、前記本体部１１０Ａからの水素ガス１０１の送出を停止するように前記操作弁１２１Ａを閉鎖制御すると共に、前記本体部１１０Ｂ内の前記放出材容器１１２α，１１２β内に充填されている水素ガス１０１を予め設定された規定流量Ｆｓ１で引き続き送出するように前記操作弁１２１Ｂを制御する（Ｓ２２１）。 In this way, the hydrogen gas 101 filled in the release material containers 112α and 112β of the main body 110A is sent out, and the pressure Ph1 of the hydrogen gas 101 in the release material containers 112α and 112β of the main body 110A is released. When it becomes less than the lower limit pressure value Pb (for example, 0.6 MPa) (Ph1 <Pb) (S112), the control device 230 sends out the hydrogen gas 101 from the main body 110A based on the information from the pressure sensor 131A. The operation valve 121A is closed and controlled so as to stop the operation valve 121A, and the hydrogen gas 101 filled in the release material containers 112α and 112β in the main body 110B is continuously delivered at a preset specified flow rate Fs1. Controls the operating valve 121B (S221).

このようにして前記本体部１１０Ｂの前記放出材容器１１２α，１１２β内に充填された水素ガス１０１を送出して、当該本体部１１０Ｂの当該放出材容器１１２α，１１２β内の水素ガス１０１の圧力Ｐｈ１が下限圧力値Ｐｂ（例えば０．６ＭＰａ）未満（Ｐｈ１＜Ｐｂ）になると（Ｓ２２２）、前記制御装置２３０は、前記圧力センサ１３１Ｂからの情報に基づいて、前記本体部１１０Ａの前記格納容器１１１の径方向内寄りに位置する前記放出材容器１１２α内の前記吸蔵材容器１１３αへ水素ガス１０１を予め設定された規定流量Ｆｓ２で供給するように前記操作弁１２２αＡを制御すると共に、当該本体部１１０Ａの前記放出材容器１１２α内の水素ガス放出材１０２から発生した水素ガス１０１を前記本体部１１０Ｂの前記格納容器１１１の径方向内寄りに位置する前記放出材容器１１２α内へ送給するように前記操作弁２２３Ａ，２２３Ｂを制御する（Ｓ２１３）。 In this way, the hydrogen gas 101 filled in the release material containers 112α and 112β of the main body 110B is sent out, and the pressure Ph1 of the hydrogen gas 101 in the release material containers 112α and 112β of the main body 110B is released. When it becomes less than the lower limit pressure value Pb (for example, 0.6 MPa) (Ph1 <Pb) (S222), the control device 230 has the diameter of the storage container 111 of the main body 110A based on the information from the pressure sensor 131B. The operation valve 122αA is controlled so that the hydrogen gas 101 is supplied to the storage material container 113α in the release material container 112α located inward in the direction at a preset specified flow rate Fs2, and the main body 110A is said to have the same. The operation valve so as to supply the hydrogen gas 101 generated from the hydrogen gas release material 102 in the release material container 112α into the release material container 112α located inward in the radial direction of the storage container 111 of the main body 110B. 223A and 223B are controlled (S213).

これにより、前記本体部１１０Ａの前記放出材容器１１２α内の水素ガス放出材１０２から発生した水素ガス１０１は、前記本体部１１０Ｂの前記放出材容器１１２α内を流通することにより、その熱を当該本体部１１０Ｂの当該放出材容器１１２α内の水素ガス放出材１０２の予熱に使用されてから、外部へ送出される。 As a result, the hydrogen gas 101 generated from the hydrogen gas release material 102 in the release material container 112α of the main body 110A circulates in the release material container 112α of the main body 110B, and the heat is transferred to the main body. It is used for preheating the hydrogen gas release material 102 in the release material container 112α of the part 110B, and then is sent to the outside.

そして、前記制御装置２３０は、前述した実施形態の場合と同様に、前記圧力センサ１３３αＡからの情報に基づいて、前記本体部１１０Ａの前記吸蔵材容器１１３α内の圧力Ｐｈ２が基準圧力値Ｐｓ（例えば０．１ＭＰａ）以下（Ｐｈ２≦Ｐｓ）であるか否か確認し（Ｓ１１４）、当該本体部１１０Ａの当該吸蔵材容器１１３α内の圧力Ｐｈ２が基準圧力値Ｐｓ以下であると、前記圧力センサ１３１Ｂからの情報に基づいて、当該本体部１１０Ｂの前記放出材容器１１２α内の水素ガス１０１の圧力Ｐｈ１が上限圧力値Ｐｔ（例えば３ＭＰａ）と下限圧力値Ｐｂ（例えば０．６ＭＰａ）との間となるように（Ｐｂ≦Ｐｈ１≦Ｐｔ）、前記操作弁１２１Ｂ，１２２αＡを制御する（Ｓ１１５）。 Then, in the control device 230, the pressure Ph2 in the storage material container 113α of the main body 110A is the reference pressure value Ps (for example, based on the information from the pressure sensor 133αA, as in the case of the above-described embodiment. It is confirmed whether or not it is 0.1 MPa) or less (Ph2 ≦ Ps) (S114), and when the pressure Ph2 in the storage material container 113α of the main body 110A is not more than the reference pressure value Ps, the pressure sensor 131B The pressure Ph1 of the hydrogen gas 101 in the release material container 112α of the main body 110B is set between the upper limit pressure value Pt (for example, 3 MPa) and the lower limit pressure value Pb (for example, 0.6 MPa). (Pb ≦ Ph1 ≦ Pt), the operating valves 121B and 122αA are controlled (S115).

このように前記本体部１１０Ａの前記吸蔵材容器１１３α内への水素ガス１０１の送給を行っているときに、当該本体部１１０Ａの当該吸蔵材容器１１３α内の温度Ｔｈ１が上限温度値Ｔｔ（例えば２５０℃）を超えてしまうと（Ｔｔ＜Ｔｈ１）（Ｓ１１６）、前記制御装置２３０は、前述した実施形態の場合と同様に、前記温度センサ１３２αＡからの情報に基づいて、当該本体部１１０Ａの当該吸蔵材容器１１３α内への水素ガス１０１の送給を停止するように前記操作弁１２２αＡを閉鎖制御する（Ｓ１１７）。 When the hydrogen gas 101 is being supplied into the storage material container 113α of the main body 110A in this way, the temperature Th1 in the storage material container 113α of the main body 110A is the upper limit temperature value Tt (for example,). When the temperature exceeds (250 ° C.) (Tt <Th1) (S116), the control device 230 uses the information from the temperature sensor 132αA based on the information from the temperature sensor 132αA, as in the case of the above-described embodiment. The operation valve 122αA is closed and controlled so as to stop the supply of the hydrogen gas 101 into the storage material container 113α (S117).

そして、前記本体部１１０Ａの前記吸蔵材容器１１３α内の温度Ｔｈ１が下限温度値Ｔｂ（例えば１００℃）未満（Ｔｈ１＜Ｔｂ）になると（Ｓ１１８）、前記制御装置２３０は、前述した実施形態の場合と同様に、前記温度センサ１３２αＡからの情報に基づいて、当該本体部１１０Ａの当該吸蔵材容器１１３α内への水素ガス１０１の送給を再開するように前記操作弁１２２αＡを制御し（Ｓ１１９）、前記ステップＳ１１４に戻る。 Then, when the temperature Th1 in the storage material container 113α of the main body 110A becomes less than the lower limit temperature value Tb (for example, 100 ° C.) (Th1 <Tb) (S118), the control device 230 is the case of the above-described embodiment. Similarly, based on the information from the temperature sensor 132αA, the operation valve 122αA is controlled so as to restart the supply of the hydrogen gas 101 into the storage material container 113α of the main body 110A (S119). The process returns to step S114.

このような前記本体部１１０Ａの前記吸蔵材容器１１３α内への水素ガス１０１の送給により、当該本体部１１０Ａの当該吸蔵材容器１１３α内の水素ガス吸蔵材１０３が水素１０１を吸蔵可能な上限容量にまで達すると、当該本体部１１０Ａの当該吸蔵材容器１１３α内の圧力Ｐｈ２が次第に上昇して、基準圧力値Ｐｓ（例えば０．１ＭＰａ）を超えるようになるので（Ｐｓ＜Ｐｈ２）、前記制御装置２３０は、前述した実施形態の場合と同様に、前記圧力センサ１３３αＡからの情報に基づいて、前記本体部１１０Ａの前記格納容器１１１の径方向外寄りに位置する前記放出材容器１１２β内の前記吸蔵材容器１１３βへ水素ガス１０１を予め設定された規定流量Ｆｓ２で供給するように前記操作弁１２２βＡを制御する（Ｓ１２３）。 By supplying the hydrogen gas 101 into the storage material container 113α of the main body 110A, the hydrogen gas storage material 103 in the storage material container 113α of the main body 110A can store hydrogen 101. When the pressure reaches up to, the pressure Ph2 in the storage material container 113α of the main body 110A gradually rises and exceeds the reference pressure value Ps (for example, 0.1 MPa) (Ps <Ph2). As in the case of the above-described embodiment, the 230 is the occlusion in the release material container 112β located on the radial side of the storage container 111 of the main body 110A based on the information from the pressure sensor 133αA. The operation valve 122βA is controlled so that the hydrogen gas 101 is supplied to the material container 113β at a preset specified flow rate Fs2 (S123).

これにより、前記本体部１１０Ａの前記放出材容器１１２β内の水素ガス放出材１０２から発生した水素ガス１０１は、当該本体部１１０Ａの前記放出材容器１１２α内を経由して前記本体部１１０Ｂの前記放出材容器１１２α内を流通することにより、その熱を当該本体部１１０Ｂの当該放出材容器１１２α内の水素ガス放出材１０２の予熱に使用されてから、外部へ送出される。 As a result, the hydrogen gas 101 generated from the hydrogen gas release material 102 in the release material container 112β of the main body 110A passes through the release material container 112α of the main body 110A and is released from the main body 110B. By circulating in the material container 112α, the heat is used for preheating the hydrogen gas releasing material 102 in the releasing material container 112α of the main body 110B, and then is sent to the outside.

そして、前記制御装置２３０は、前記本体部１１０Ａの前記吸蔵材容器１１３αの場合と同様、すなわち、前述した実施形態の場合と同様に、前記圧力センサ１３３βＡからの情報に基づいて、当該本体部１１０Ａの前記吸蔵材容器１１３β内の圧力Ｐｈ３が基準圧力値Ｐｓ（例えば０．１ＭＰａ）以下（Ｐｈ３≦Ｐｓ）であるか否か確認し（Ｓ１２４）、当該本体部１１０Ａの当該吸蔵材容器１１３β内の圧力Ｐｈ３が基準圧力値Ｐｓ以下であると、当該本体部１１０Ａの前記放出材容器１１２αの場合と同様、すなわち、前述した実施形態の場合と同様に、前記圧力センサ１３１Ｂからの情報に基づいて、前記本体部１１０Ｂの前記放出材容器１１２β内の水素ガス１０１の圧力Ｐｈ１が上限圧力値Ｐｔ（例えば３ＭＰａ）と下限圧力値Ｐｂ（例えば０．６ＭＰａ）との間となるように（Ｐｂ≦Ｐｈ１≦Ｐｔ）、前記操作弁１２１Ｂ，１２２βＡを制御する（Ｓ１２５）。 Then, the control device 230 is the same as the case of the storage material container 113α of the main body 110A, that is, as in the case of the above-described embodiment, based on the information from the pressure sensor 133βA, the main body 110A It is confirmed whether or not the pressure Ph3 in the storage material container 113β is equal to or less than the reference pressure value Ps (for example, 0.1 MPa) (Ph3 ≦ Ps) (S124), and the pressure Ph3 in the storage material container 113β of the main body 110A is When the pressure Ph3 is equal to or less than the reference pressure value Ps, the pressure sensor 131B is based on the information from the pressure sensor 131B, as in the case of the release material container 112α of the main body 110A, that is, as in the case of the above-described embodiment. The pressure Ph1 of the hydrogen gas 101 in the release material container 112β of the main body 110B is between the upper limit pressure value Pt (for example, 3 MPa) and the lower limit pressure value Pb (for example, 0.6 MPa) (Pb ≦ Ph1 ≦). Pt) controls the operating valves 121B and 122βA (S125).

このように前記本体部１１０Ａの前記吸蔵材容器１１３β内への水素ガス１０１の送給を行っているときに、当該本体部１１０Ａの当該吸蔵材容器１１３β内の温度Ｔｈ２が上限温度値Ｔｔ（例えば２５０℃）を超えてしまうと（Ｔｔ＜Ｔｈ２）（Ｓ１２６）、当該本体部１１０Ａの前記吸蔵材容器１１３αの場合と同様、すなわち、前述した実施形態の場合と同様に、前記制御装置２３０は、前記温度センサ１３２βＡからの情報に基づいて、上記本体部１１０Ａの上記吸蔵材容器１１３β内への水素ガス１０１の送給を停止するように前記操作弁１２２βＡを閉鎖制御する（Ｓ１２７）。 When the hydrogen gas 101 is being supplied into the storage material container 113β of the main body 110A in this way, the temperature Th2 in the storage material container 113β of the main body 110A is the upper limit temperature value Tt (for example,). When the temperature exceeds (250 ° C.) (Tt <Th2) (S126), the control device 230 receives the same as in the case of the storage material container 113α of the main body 110A, that is, as in the case of the above-described embodiment. Based on the information from the temperature sensor 132βA, the operation valve 122βA is closed and controlled so as to stop the supply of the hydrogen gas 101 into the storage material container 113β of the main body 110A (S127).

そして、前記本体部１１０Ａの前記吸蔵材容器１１３β内の温度Ｔｈ２が下限温度値Ｔｂ（例えば１００℃）未満（Ｔｈ２＜Ｔｂ）になると（Ｓ１２８）、当該本体部１１０Ａの前記吸蔵材容器１１３αの場合と同様、すなわち、前述した実施形態の場合と同様に、前記制御装置２３０は、前記温度センサ１３２βＡからの情報に基づいて、上記本体部１１０Ａの上記吸蔵材容器１１３β内への水素ガス１０１の送給を再開するように前記操作弁１２２βＡを制御し（Ｓ１２９）、前記ステップＳ１２４に戻る。 When the temperature Th2 in the storage material container 113β of the main body 110A becomes less than the lower limit temperature value Tb (for example, 100 ° C.) (Th2 <Tb) (S128), the case of the storage material container 113α of the main body 110A That is, as in the case of the above-described embodiment, the control device 230 sends the hydrogen gas 101 into the storage material container 113β of the main body 110A based on the information from the temperature sensor 132βA. The operation valve 122βA is controlled so as to restart the supply (S129), and the process returns to the step S124.

このような前記本体部１１０Ａの前記吸蔵材容器１１３β内への水素ガス１０１の送給により、当該本体部１１０Ａの当該吸蔵材容器１１３β内の水素ガス吸蔵材１０３が水素１０１を吸蔵可能な上限容量にまで達すると、当該本体部１１０Ａの当該吸蔵材容器１１３β内の圧力Ｐｈ３が次第に上昇して、基準圧力値Ｐｓ（例えば０．１ＭＰａ）を超えるようになるので（Ｐｓ＜Ｐｈ３）、前記制御装置２３０は、前記圧力センサ１３３βＡからの情報に基づいて、前記本体部１１０Ｂの前記格納容器１１１の径方向内寄りに位置する前記放出材容器１１２α内の前記吸蔵材容器１１３αへ水素ガス１０１を予め設定された規定流量Ｆｓ２で供給するように前記操作弁１２２αＢを制御する（Ｓ２３３）。 By supplying the hydrogen gas 101 into the storage material container 113β of the main body 110A, the hydrogen gas storage material 103 in the storage material container 113β of the main body 110A can store hydrogen 101. When the pressure reaches up to, the pressure Ph3 in the storage material container 113β of the main body 110A gradually rises and exceeds the reference pressure value Ps (for example, 0.1 MPa) (Ps <Ph3). Based on the information from the pressure sensor 133βA, 230 sets the hydrogen gas 101 in advance in the storage material container 113α in the release material container 112α located inward in the radial direction of the storage container 111 of the main body 110B. The operation valve 122αB is controlled so as to supply at the specified specified flow rate Fs2 (S233).

そして、前記制御装置２３０は、前記本体部１１０Ａの前記放出材容器１１２α及び前記吸蔵材容器１１３αの場合と同様に、前記ステップＳ１１４〜Ｓ１１９と同様なステップＳ２３４〜Ｓ２３９を前記本体部１１０Ｂの前記放出材容器１１２α及び前記吸蔵材容器１１３αに行うことにより、当該本体部１１０Ｂの当該放出材容器１１２α内の水素ガス放出材１０２から水素ガス１０１を発生させて、当該本体部１１０Ｂから外部へ直接的に送出する。 Then, the control device 230 releases steps S234 to S239 similar to steps S114 to S119 of the main body 110B in the same manner as in the case of the release material container 112α and the storage material container 113α of the main body 110A. By performing this on the material container 112α and the storage material container 113α, hydrogen gas 101 is generated from the hydrogen gas releasing material 102 in the releasing material container 112α of the main body 110B, and the hydrogen gas 101 is directly generated from the main body 110B to the outside. Send out.

このような前記本体部１１０Ｂの前記放出材容器１１２α内の水素ガス放出材１０２からの水素ガス１０１の外部への直接的な送出を行い、当該本体部１１０Ｂの前記吸蔵材容器１１３α内の水素ガス吸蔵材１０３が水素１０１を吸蔵可能な上限容量にまで達すると、前記制御装置２３０は、前記圧力センサ１３３αＢからの情報に基づいて、前記本体部１１０Ｂの前記格納容器１１１の径方向外寄りに位置する前記放出材容器１１２β内の前記吸蔵材容器１１３βへ水素ガス１０１を予め設定された規定流量Ｆｓ２で供給するように前記操作弁１２２βＢを制御する（Ｓ２４３）。 The hydrogen gas 101 is directly sent out from the hydrogen gas release material 102 in the release material container 112α of the main body 110B to the outside, and the hydrogen gas in the storage material container 113α of the main body 110B is performed. When the storage material 103 reaches the upper limit capacity capable of storing hydrogen 101, the control device 230 is positioned outside the radial direction of the storage container 111 of the main body 110B based on the information from the pressure sensor 133αB. The operation valve 122βB is controlled so that the hydrogen gas 101 is supplied to the storage material container 113β in the release material container 112β at a predetermined predetermined flow rate Fs2 (S243).

そして、前記制御装置２３０は、前記本体部１１０Ａの前記放出材容器１１２β及び前記吸蔵材容器１１３βの場合と同様に、前記ステップＳ１２４〜Ｓ１２９と同様なステップＳ２４４〜Ｓ２４９を行うことにより、当該本体部１１０Ｂの当該放出材容器１１２β内の水素ガス放出材１０２から水素ガス１０１を発生させて、当該本体部１１０Ｂから外部へ直接的に送出する。 Then, the control device 230 performs the same steps S244 to S249 as in steps S124 to S129, as in the case of the release material container 112β and the storage material container 113β of the main body 110A, thereby causing the main body. Hydrogen gas 101 is generated from the hydrogen gas release material 102 in the release material container 112β of 110B, and is sent directly to the outside from the main body 110B.

このような前記本体部１１０Ｂの前記放出材容器１１２β内の水素ガス放出材１０２からの水素ガス１０１の外部への直接的な送出を行い、当該本体部１１０Ｂの前記吸蔵材容器１１３β内の水素ガス吸蔵材１０３が水素１０１を吸蔵可能な上限容量にまで達すると、前記制御装置２３０は、前記圧力センサ１３３βＢからの情報に基づいて、運転を終了する。 The hydrogen gas 101 is directly sent out from the hydrogen gas release material 102 in the release material container 112β of the main body 110B to the outside, and the hydrogen gas in the storage material container 113β of the main body 110B is performed.

The gas 101 was circulated in the release material container 112α of the other main body 110B and then sent out to the outside.

このため、本実施形態に係る水素ガス供給装置２００では、本体部１１０Ａの放出材容器１１２α，１１２β内の水素ガス放出材１０２から発生した水素ガス１０１の熱を利用して本体部１１０Ｂの放出材容器１１２α内の水素ガス放出材１０２を予熱することができる。 Therefore, in the hydrogen gas supply device 200 according to the present embodiment, the release material of the main body 110B is utilized by utilizing the heat of the hydrogen gas 101 generated from the hydrogen gas release material 102 in the release material containers 112α and 112β of the main body 110A. The hydrogen gas release material 102 in the container 112α can be preheated.
