<P>PROBLEM TO BE SOLVED: To provide a laminated electrolyte film for a fuel cell which internally alleviates a dimensional change caused when wetted. <P>SOLUTION: The laminated electrolyte film for the fuel cell is a plurality of laminated solid polymer electrolyte films, and laminated such that the neighboring solid polymer electrolyte film in swelling are laminated so as to mutually suppress the dimensional change of the other solid polymer electrolyte film when wetted, and the solid polymer electrolyte films are laminated so that stretched directions will cross in the case of an unidirectionally stretched electrolyte film 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
