    摘要: A solid electrolyte film according to the present invention includes a resin having a repeating unit of the general formula (1) containing a bis(perfluoroalkanesulfonyl)methide moiety: where R represents a hydrogen atom or a methyl group; Y represents an oxygen atom or NH; Rf represents a C1-C4 perfluoroalkyl group; and W represents either a C2-C4 straight or C3-C4 branched alkylene group or a C5-C8 cyclic hydrocarbon group as a linking group, which may have a branched chain or a cross-linking structure.This solid electrolyte film combines high proton conductivity with low methanol permeability for prevention of methanol crossover and can suitably be used for a direct methanol fuel cell etc.
