PROBLEM TO BE SOLVED: To keep the characteristics of the fuel electrode in a good condition for a solid electrolyte fuel cell for a long time. SOLUTION: This fuel electrode comprises a fuel electrode and an air electrode with solid electrolyte therebetween of primarily zirconia. And more than one kind among MgO, CaO, SrO, Y2 O3 , La2 O3 , Sc2 O3 , Al2 O3 , or tungsten powder or titanium powder is added to the material powder including at least nickel or nickel oxide, to make the base material for the film to be formed on the surface of solid electrolyte. Since high melting point powder is included in a condition of high dispersion, the sintering and coagulation of nickel is suppressed or prevented to keep the characteristics as the fuel cell electrode in a good condition for a long time. |
