摘要： There is provided a film electrode assembly for a fuel cell capable of preventing a polymer electrolyte film from being exposed. The film electrode assembly includes: a main body portion of a film electrode assembly having a polymer electrolyte film, and a pair of electrode layers having catalyst layers placed on the two surfaces of the polymer electrolyte film on the inner side from the peripheral edge portion thereof and diffusion layers each having a peripheral edge protruding from the catalyst layer, which are laminated on one another, with a gap being formed between the protruding portion of the diffusion layer and the peripheral edge portion of the polymer electrolyte film; a frame member that sandwiches the peripheral edge portion of the polymer electrolyte film between the paired electrode layers with a gap therebetween, and is formed so as to surround an outer edge of the polymer electrolyte film; and gaskets made of a thermoplastic resin, which are placed on the two surfaces of the frame member. Each gasket includes an annular portion that covers the peripheral edge portion of the main body portion of the film electrode assembly over the entire circumference thereof along the inner edge of the frame member and a gap filling portion that fills the gap.

摘要： A MEA-frame assembly is arranged in a mold for injection molding to form a first flow passage arranged so as to extend along the outer periphery of an electrode between the outer periphery of the electrode and the inner periphery of a frame, a second flow passage arranged so as to extend along an inner elastic member between the inner periphery and outer periphery of the frame and a plurality of connecting flow passages which communicate the first flow passage with the second flow passage. An elastic resin is injected into the first flow passage to fill the first flow passage with the elastic resin and to fill the second flow passage with the elastic resin through each of the communicating flow passages, thereby an elastic member which hermetically seals the space between the MEA-frame assembly and the separator is integrally formed.
