Abstract

PURPOSE:To obtain the negative electrode of a fuel cell with the excellent performance and high productivity by mixing the metal powder coated with the ceramic fine powder on the surface and a ceramic powder material, molding the mixture in an electrode shape, incorporating the molded electrode in a battery, then burning a molding auxiliary. CONSTITUTION:After the metal powder material coated with the ceramic fine powder on the surface and the ceramic powder material are mixed, the mixture is molded in an electrode shape with at least a molding auxiliary or the like, the molded electrode is incorporated in a battery, then an organic matter such as the molding auxiliary is burnt. As soon as the molding auxiliary in the electrode is removed, metal powder particles serving as the electrode material are sintered at the portion not coated with the ceramic fine powder. The electrode can thereby perform its function, the ceramic coated on the metal surface and the mixed ceramic powder prevent the over-sintering, and the mixed ceramic powder prevents the creep-resistant phenomenon.
