る。Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a solid oxide fuel cell.
従来の技術 上記高温固体電解質型燃料電池（SOFC）は、リン酸型
及び溶融炭酸塩型燃料電池に次ぐ第三世代の燃料電池と
して注目されている。2. Description of the Related Art The high-temperature solid oxide fuel cell (SOFC) has attracted attention as a third-generation fuel cell next to a phosphoric acid type and a molten carbonate type fuel cell.
ここで、上記電池は酸化物固体（Y2O3安定化ZrO2等）
から成るので、電解液の蒸発やクリーページを回避する
ことができる。したがって、上記従来型電池の課題であ
る電解質損失を解消できる。加えて、作動温度が約1000
℃の高温であるため、発電効率が高くなるという利点も
ある。Here, the battery is an oxide solid (Y 2 O 3 stabilized ZrO 2 etc.)
, It is possible to avoid evaporation of the electrolyte and creepage. Therefore, the electrolyte loss, which is a problem of the conventional battery, can be solved. In addition, the operating temperature is about 1000
Because of the high temperature of ° C., there is also an advantage that power generation efficiency is increased.
しかしながら、上記固体電解質型燃料電池では、以下
に示す課題を有している。However, the solid oxide fuel cell has the following problems.
構成が全て固体なので、構成部材間同士の密着性が悪
くなる。Since the configuration is all solid, the adhesion between the constituent members deteriorates.
電解質が液体である従来の燃料電池に比べて界面（三
相界面）の形成が困難なので、有効反応面積が小さくな
る。Since it is more difficult to form an interface (three-phase interface) than in a conventional fuel cell in which the electrolyte is a liquid, the effective reaction area is reduced.
これらのことから、接触抵抗や反応抵抗が増大し、単
位体積当たりの出力が低下する。For these reasons, contact resistance and reaction resistance increase, and output per unit volume decreases.
そこで、燃料極としてNiとZrO2とのサーメットを用い

緩和することや、反応面積の増大を図るようなもの、及
び酸化剤極に用いる粉末を熱処理するような方法が提案
されている。Therefore, by using a cermet of Ni and ZrO 2 as the fuel electrode, it is possible to reduce the difference in the coefficient of thermal expansion between the fuel electrode and the electrolyte plate, to increase the reaction area, and to use the oxidizer electrode. Methods have been proposed in which the powder used is heat-treated.
発明が解決しようとする課題 しかしながら、上記構造のものであっても、異種接合
故やはり熱膨張率に差異が生じる等の理由により、長期

効反応面積を余り大きくすることができない。これらの
ことから、長期間使用すると、接触抵抗や反応抵抗が増
大するという課題を有している。Problems to be Solved by the Invention However, even with the above structure, stable characteristics cannot be obtained for a long period of time due to the difference in thermal expansion coefficient due to the heterogeneous bonding. Further, since the formation of the interface is difficult only by simply using cermet, the effective reaction area cannot be made too large. For these reasons, there is a problem that the contact resistance and the reaction resistance increase when used for a long time.
本発明は、かかる現状に鑑みてなされたものであり、
接触抵抗や反応抵抗が増大するのを長期に渡って抑制す

れば、同種接合となるので、密着性向上の効果は顕著と
なる。According to the method for manufacturing a solid oxide fuel cell, a soft green sheet is used as a material for forming the electrodes and the electrolyte, and the material is heated and pressurized. Along with the shape of the mesh even after firing, so that the adhesion between the electrodes and the solid electrolyte plate is improved. As a result,
Since the increase in contact resistance and reaction resistance can be suppressed over a long period of time, battery characteristics can be dramatically improved. In particular, if the mesh is made of ceramics, the same type of bonding is achieved, so that the effect of improving the adhesion is remarkable.
