PURPOSE:To obtain excellent electrochemical reaction and conductivity and prevent the breakage of a solid electrolyte or an electrode by thermal stress by molding ceramic grains coated with nickel grains on the surface into a plate shape, and baking it. CONSTITUTION:Ceramic grains 12 coated with nickel grains 13 on the surface are molded into a plate-shaped fuel electrode 11, and it is baked. Ceramic grains of alumina or silicon carbide having a smaller linear expansion coefficient than that of a normal solid electrolyte material, e.g. yttria stabilized zirconia or ceramic grains of YSZ itself or partially stabilized zirconia are used for ceramic grains 12. |
