A fuel electrode of solid electrolyte type fuel cells which is made of a cermet composed of yttria-stabilized zirconia containing a transition metal dissolved therein and nickel (Ni) or a cermet composed of yttria-stabilized zirconia containing a transition metal dissolved therein, Ni and cerium oxide containing a divalent or trivalent metal dissolved therein can be prepared by adding a solution of an organoyttrium compound and a solution of an organic transition-metal compound to a solution of an organozirconium compound to prepare a mixed solution of organometallic compounds containing zirconium, yttrium and transition metal as the metal components, adding NiO powder or a powder mixture of NiO powder with cerium oxide powder containing a divalent or trivalent metal oxide dissolved therein to the above mixed solution to prepare a slurry, and subjecting this slurry to hydrolysis, polycondensation, pyrolysis, annealing and reduction successively. This fuel electrode can be formed on a solid electrolyte layer by screen process printing. |
