POLYMER ELECTROLYTE FUEL CELL AND MANUFACTURING METHOD THEREOF

摘要

An MEA having an MEA body part 5C; a frame 6 made of a plate-like thermoplastic resin; and gaskets 7 formed on opposed surfaces of the frame 6 so as to hold the frame 6 between. The gaskets 7 each have an annular portion 7A that is annularly formed so as to extend along the inner periphery of the frame 6 and elongated portions 7B1 to 7B8 that extend from the annular portion 7A and come into contact with the side faces of an associated electrode layer 5C after passing over the inner periphery of the frame 6 and a peripheral region 5D of a polymer electrolyte membrane.
