ABSTRACT:
A polymer electrolyte membrane for use in a fuel cell and a method of producing a polymer electrolyte membrane. The method includes preparing a phosphate monomer solution by dissolving an initiator and a phosphate monomer containing at least one phosphoric acid group and at least one unsaturated bond in a solvent, impregnating a porous polymer matrix with the phosphate monomer solution, polymerizing the impregnated phosphate monomer, and impregnating the result of polymerization with a phosphoric acid.
