<p>PURPOSE: To provide a cell of a solid polymer fuel cell with high output by increasing porosity of an electrode catalyst layer and enhancing reaction gas distributing capability. CONSTITUTION: When an electrode catalyst layer 3 is formed on a solid polymer electrolyte film 1, by using dispersion plating relating to chemical plating, an electrode catalyst salt is adsorbed together with polymer particles 2, then the polymer particles 2 are removed in an acidic solution to obtain a porous electrode catalyst layer 3. Or porous organic polymer resin is formed on the solid polymer electrolyte film 1, then chemical plating is conducted to form the electrode catalyst layer on the surface of the porous organic polymer resin layer, or on the surfaces of the porous organic polymer resin layer and the solid polymer electrolyte film 1.</p> |
