<P>PROBLEM TO BE SOLVED: To provide a gasket for polymer electrolyte fuel cell of multiple seal structure in which low fastening power, compaction of a stack, and enhancement in durability of a seal lip are achieved. <P>SOLUTION: The seal member 14 molded on the outer periphery of an MEA 9 integrally therewith is provided continuously with seal lips having sealability in a plane in parallel with each other. One of two rows of seal lips 15, 16 is arranged to have a lower seal height when compared with the other. The height at a part between the seal lips is made lower than the height of fastening the seal lips by means of the separators on the front and back sides of the MEA. <P>COPYRIGHT: (C)2013,JPO&INPIT |
