PROBLEM TO BE SOLVED: To provide a membrane with high proton-conductivity consisting of aliphatic hydrocarbon polymer, a proton-conductive film obtained by a hear treatment of the membrane and manufacturing methods for the same. SOLUTION: A proton-conductive film is, as its features, comprised of a porous aliphatic hydrocarbon polymer membrane and a polymer having a sulfonic acid radical content carried into cells of the porous membrane. The proton- conductive film is heated to melt and/or contract so as to collapse the cells, thereby obtaining a proton-conductive film. |
