Abstract

PURPOSE:To obtain an electrode having high strength and porosity, by forming on an expanded metal made of a specific acid-resistant metal a layer of the same kind of metallic powder as said expanded metal, and then rendering them into a united body through sintering the same. CONSTITUTION:After forming slits in a regular pattern in a thin plate of an acid- resistant metal such as Ta, Nb, or the like, the plate is expanded to obtain an expanded metal on which a layer of the same kind of metallic powder as said metal is formed, for example, to a thickness of 100-500mg/cm<2>. Thereafter, the plate is integrated by a vacuum sintering to obtain an electrode. According to this constitution, an electrode base consisting of a fuel pole 3 and oxidizing agent pole 5 has high strength and porosity (70% or higher) and is provided with a sufficient reaction field to an electrode catalyst, thus improving the electrode performance of a fuel battery.
