<P>PROBLEM TO BE SOLVED: To provide a laminated electrolytic film, which is excellent in electric power generating characteristics. <P>SOLUTION: [1] The laminated film is characterized in that a polymer electrolytic film (a) and an aromatic polymer film (b) having super-strong acid radicals on its side chains are laminated. [2] The laminated film described above [1] is characterized in that the film (b) is composed of the aromatic polymer shown by formula (1): -(A-Z)<SB>m</SB>-(A'-Z')<SB>n</SB>- (1) (wherein A shows a divalent aromatic group, A' shows a divalent aromatic group having substituted super-strong acid groups, Z and Z' show independently direct coupled or divalent groups respectively, m and n show the number of repetition units, wherein n is within the range from 10 to 100,000 and the n repetition units may be the same or different, and m is within the range from 0 to 100,000 and the m repetition units may be the same or different). <P>COPYRIGHT: (C)2004,JPO |
