Abstract: PURPOSE: A method for preparing a composite polymer membrane of polymer electrolyte membrane fuel cell(PEMFC) is provided, which lowers a price of the polymer membrane, produces the electrolytic polymer membrane having a relatively thin thickness and reduces expansion and contraction of the polymer membrane. And a method for preparing a composite polymer membrane/electrode assembly by using the same is provided. CONSTITUTION: The method for preparing a composite polymer membrane comprises steps of: (i) hot pressing or rolling a perfluorosulfonylfluoride/TFE copolymer resin at 200-250 deg.C to obtain a pre-formed precursor sheet; (ii) after inserting a porous membrane in the center of the pre-formed precursor sheet, hot pressing or rolling it to obtain a composite sheet of the pre-formed precursor and the porous membrane; (iii) treating the composite sheet with an aqueous solution of sodium hydroxide in a 5-30 weight ratio to convert the composite pre-formed sheet consisting of the composite perfluorosulfonylfluoride/TFE copolymer resin into a Na+ formed composite perfluorosulfonate polymer membrane; and (iv) hydrating the Na+ formed composite perfluorosulfonate polymer membrane to convert it into a H+ formed composite perfluorosulfonate polymer membrane. The composite polymer membrane/electrode assembly is prepared by the steps of: (i) hot pressing or rolling a perfluorosulfonylfluoride/TFE copolymer resin at 200-250 deg.C to obtain a pre-formed precursor sheet; (ii) after inserting a porous membrane in the center of the pre-formed precursor sheet, hot pressing or rolling it to obtain a composite sheet of the pre-formed precursor and the porous membrane; (iii) treating the composite sheet with an aqueous solution of sodium hydroxide in a 5-30 weight ratio to convert the composite pre-formed sheet consisting of the composite perfluorosulfonylfluoride/TFE copolymer resin into a Na+ formed composite perfluorosulfonate polymer membrane; (iv) coating the Na+ formed composite perfluorosulfonate polymer membrane with a platinum catalyst ink; and (v) hot pressing the catalyst ink coated composite polymer membrane at 120-200 deg.C to produce a composite polymer membrane/electrode assembly.
