PURPOSE:To prevent coagulation of metal, prevent degradation of electrode performance, and increase strength and durability by constituting a fuel electrode plate of a metal wherein a thin film-shape YSZ is precipitated on a surface of a particle. CONSTITUTION:First, powder of metal such as Ni or metallic oxide such as NiO is mixed with a solution of an organic metallic compound wherein a metal which produces a film or particulates of YSZ by thermal decomposition is combined with an organic group via oxygen. Then, a solvent is removed and the mixture is pulverized to form a granulating body, which is placed in a metal die and subjected to press forming and baking. A fuel electrode plate of a support film type solid electrolyte fuel cell is thereby completed and this electrode plate is adopted as a base board, on a surface of which an electrolyte film layer is formed. Since particulates or a thin film of YSZ are precipitated on a surface of a metal such as Ni in the fuel electrode to cover a whole surface of a metal particle, coagulation of the metal particles with each other is prevented and the electrode becomes difficult to be separated. Consequently, a fuel electrode plate having large strength and durability can be obtained. |
