POLYMER ELECTROLYTE FUEL CELL AND ELECTRODE/FILM/FRAME ASSEMBLY MANUFACTURING METHOD

摘要

An MEA/frame assembly is arranged in an injection molding die to form a first channel extending along an outer brim of an electrode portion between the outer brim of the electrode portion and an inner brim of a frame, a second channel extending along an inner side elastic member between the inner and the outer brim of the frame, and a plurality of communication channels causing the first channel to communicate with the second channel. An elastic resin is introduced into the first channel so as to fill the first channel with the elastic resin and the second channel with the elastic resin via the respective communication channels, thereby forming an elastic member which seals a portion between the MEA/frame assembly and a separator as a unitary block.
