BONDED ELECTRODE/FILM FOR SOLID POLYMER FUEL CELL AND METHOD FOR PRODUCING THE SAME

It is to provide an electrode/membrane assembly (8) for a polymer electrolyte fuel cell, comprising, as an anode (6) and/or cathode (7), a gas diffusion electrode which comprises a gas diffusion layer (5, 5') comprising a carbon cloth (1, 1') and a water repellent carbon layer (2, 2') formed on the surface of the carbon cloth, and a catalyst layer (3, 3') containing a catalyst and a fluorocarbon sulfonic acid type ion exchange resin, formed on the gas diffusion layer, and which contains a solvent-soluble fluorine-containing polymer having substantially no ion exchange group, and comprising an ion exchange membrane (4) sandwiched therebetween and bonded to each other. A polymer electrolyte fuel cell provided with the electrode/membrane assembly (8) having the above structure is excellent in durability with small deterioration in performance even when used for a long period of time.
