Abstract:
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.
