電池発電システムに関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a fuel cell power generation system provided with a mechanism for protecting a low temperature shift converter and a fuel cell during fuel cell operation.
第１図は従来の燃料電池発電システムの構成図
を示したものである。
FIG. 1 shows a configuration diagram of a conventional fuel cell power generation system.

低減する。このようにして低温シフトコンバータ
４′を出た燃料ガスＣは、燃料電池１へと供給さ
れ、ここで別途経路Ｘから供給された空気と接触
して発電がおこなわれる。空気は経路Ｘから燃料
電池１を経て経路Ｙへと排出される。 Hydrogen is supplied to the fuel cell 1 as a fuel gas, and this fuel gas is supplied via a reformer 2, a high temperature shift converter 4, and a low temperature shift converter 4'. A mixed gas A containing fuel gas and water vapor as main components is supplied to the reformer 2, and a gas B containing hydrogen, carbon monoxide, etc. is supplied to the reformer 2.
and is sent to the high temperature shift converter 4. The high-temperature shift converter 4 converts most of the carbon monoxide contained in the reformed gas B into carbon dioxide and hydrogen, and converts the carbon monoxide contained in the reformed gas B into hydrogen-rich gas B', which has an even higher hydrogen content than the reformed gas B. It is sent to the low temperature shift converter 4'. In this low-temperature shift converter 4', residual carbon monoxide in the hydrogen-rich gas B' is converted into carbon dioxide and hydrogen, so that the concentration of residual carbon monoxide is reduced to several percent or less. The fuel gas C leaving the low-temperature shift converter 4' in this manner is supplied to the fuel cell 1, where it comes into contact with air separately supplied from route X to generate electricity. Air is discharged from path X through fuel cell 1 to path Y.
一方、発電に使われた燃料ガスは燃料電池１か

必要な熱を改質器２へと供給する。 On the other hand, the fuel gas used for power generation is discharged from the fuel cell 1 and supplied to the reformer burner 3 through path D, where it is mixed with air separately supplied from path Z and combusted. Heat necessary for reforming the mixed gas A is supplied to the reformer 2.
なお低温シフトコンバータ４′から排出される
燃料ガスＣ中の一酸化炭素濃度を数パーセント以
下に下げる理由は、一酸化炭素が下流にある燃料
電池１の電極触媒を被毒させ、触媒活性を低下さ

H2OCO2＋H2の反応がおこり、一酸化炭素と
水蒸気とから二酸化炭素と水素とが生成されて、
その際反応熱が発生する。 The reason for reducing the carbon monoxide concentration in the fuel gas C discharged from the low temperature shift converter 4' to below several percent is that carbon monoxide poisons the downstream electrode catalyst of the fuel cell 1, reducing the catalyst activity. This is to prevent this from happening. In both the high temperature shift converter 4 and the low temperature shift converter 4', CO+
A reaction of H 2 OCO 2 + H 2 occurs, and carbon dioxide and hydrogen are generated from carbon monoxide and water vapor,
At this time, reaction heat is generated.

ぞれ用いられている。 In addition, the high temperature shift converter 4' and the low temperature shift converter 4' are filled with a reaction catalyst to quickly carry out the above reaction, and the high temperature shift converter 4 is filled with a catalyst that has low activity but is inexpensive and suitable for large-scale processing. However, the low-temperature shift converter 4' uses an expensive but highly active catalyst suitable for processing small quantities.

ため反応が急激に進行し、急な発熱がおきて触媒

ンバータ４′自体を破壊してしまうことがある。
In such a conventional fuel cell power generation system, the reaction conditions of the reformer 2 and the high temperature shift converter 4 are not stable during startup, shutdown, abnormality, etc., so that the amount of carbon monoxide exceeding the carbon monoxide processing capacity of the low temperature shift converter 4' is unstable. When fuel gas containing carbon monoxide is supplied to the low temperature shift converter 4', the reaction proceeds rapidly because the low temperature shift converter 4' uses a highly active catalyst, causing sudden heat generation and damaging the catalyst. This may cause damage or, in extreme cases, destroy the low temperature shift converter 4' itself.
このような事態を防止するために、従来の燃料

冷却するかの方法しか無かつた。 In order to prevent such a situation, in a conventional fuel cell power generation system, the mixed gas A of fuel gas and water vapor supplied to the reformer 2 is reduced to reduce the amount of monoxide supplied to the low-temperature shift converter 4'. The only options were to reduce the amount of carbon or to cool the low temperature shift converter 4' itself.
このような方法は本質的に低温シフトコンバー

ための弁６および弁７を設けている。 In the conventional power generation system, no attachments were installed in the connecting flow path connecting the high temperature shift converter 4 and the low temperature shift converter 4'.
In the embodiment shown in the figure, there is a bypass flow path E that branches this connection flow path, and a gas analyzer that is located in this connection flow path and detects the amount of residual carbon monoxide in the exhaust gas from the high temperature shift converter 4. A total of 5 are provided, and furthermore, a valve 6 and a valve 7 for switching between this connection flow path and the bypass flow path E are provided.

上で望ましくない値の一酸化炭素濃度である。 With this configuration, depending on the signal from the gas analyzer 5 installed downstream of the high-temperature shift converter 4, the fuel gas is normally supplied to the low-temperature shift converter by opening the valve 6 and closing the valve 7. However, in the event of an abnormality, the valve 6 is closed in response to the output signal of the gas analyzer 5, and the valve 7 is opened to bypass the fuel gas to the bypass passage E. The opening and closing operations of the valves 6 and 7 are linked, and when one is open, the other is closed. The opening/closing signals for the valves 6 and 7 are generated when the gas analyzer 5 detects the amount of carbon monoxide in the fuel gas B' and this detected value exceeds a certain value. Here, the constant value is a carbon monoxide concentration that is undesirable for maintaining the characteristics of the low temperature shift converter 4' and the fuel cell 1.

This embodiment differs from the embodiment shown in FIG. 2 in that a structure 8 is inserted into the bypass channel E. This structure 8 has a structure having a predetermined flow path volume and flow path resistance, and this flow path volume and flow path resistance are defined as the flow of fuel through the low temperature shift converter 4' and the fuel cell 1. It is set to be equal to that when gas flows. By inserting such a structure 8 into the bypass channel E, pressure fluctuations during channel switching can be minimized.

As in the case of FIG. 2 and FIG. 3, the operation is performed to selectively switch whether the fuel gas B' discharged from the high-temperature shift converter 4 flows to the low-temperature shift converter 4' or to the bypass passage E. .

As described above based on the embodiments, the present invention includes a gas analyzer that detects the carbon monoxide concentration in the fuel gas discharged from the high-temperature shift converter, and a gas analyzer that detects the carbon monoxide concentration in the fuel gas discharged from the high-temperature shift converter. Since a gas switching means is provided to switch the flow path from the flow path to the fuel cell to the bypass flow path, malfunctions of the reformer and high-temperature shift converter can be avoided when the power generation system is started, stopped, unsteady, abnormal, etc. Even if the carbon monoxide concentration in the fuel gas increases due to stable operation, it has the advantage of preventing characteristic deterioration or destruction of the low temperature shift converter or fuel cell due to this.
