PROBLEM TO BE SOLVED: To provide a proton conductive membrane or film having durability and mechanical strength and its manufacturing method, and to provide a fuel cell using this membrane or film as a proton exchange membrane. SOLUTION: This proton conductive membrane is obtained by polymerizing a single functional monomer having a phosphate group, a phosphonate group or a phosphinate group in the side and a single functional monomer having an amine salt of the phosphate group, the phosphonate group or the phosphinate group in the side chain, in the void of a porous membrane, by producing a polymer having a part of the phosphate group in the form of an amine salt, the phosphonate group or the phosphinate group in the side chain, and by carrying the polymer in the voids of the porous membrane. The proton conductive film formed by blocking at least a part of the remaining voids of the voids of the proton conductive membrane and the manufacturing method of the proton conductive film are provided. In addition, the fuel cell using the proton conductive film as the proton exchange membrane is provided. |
