FUEL CELL RESIN FRAME EQUIPPED MEMBRANE ELECTRODE ASSEMBLY

摘要

A resin frame equipped membrane electrode assembly includes a membrane electrode assembly and a resin frame member. The membrane electrode assembly includes an anode, a cathode, and a solid polymer electrolyte membrane interposed between the anode and the cathode. The resin frame member is provided around the solid polymer electrolyte membrane. The resin frame member includes an inner extension protruding toward the outer periphery of the cathode to contact the outer end of the solid polymer electrolyte membrane. The inner extension of the resin frame member includes a plurality of columnar projections formed integrally with an adhesive surface where an adhesive layer is provided.
