<P>PROBLEM TO BE SOLVED: To provide a lamination body of solid polymer electrolyte films capable of keeping the film in humid state without arranging any humidifier necessitated in conventional fuel cell. <P>SOLUTION: The lamination body is formed by laminating cation exchange films made of polyarylene copolymer having a sulfonic acid group, and anion exchange films. The anion exchange film is selected from a group including a polyvinylpyridine film, a fluorine-based ion exchange film having ammonium salt derivative, a vinylbenzene polymer film having ammonium salt derivative, and a film formed by laminating a copolymer of chloromethylstyrene and vinylbenzene. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
