PURPOSE: A polymer composite electrolyte membrane is provided to ensure excellent ion conductivity and mechanical properties at a high temperature and non humidification condition, and to prevent the poisoning of a catalyst. CONSTITUTION: A polymer composite electrolyte membrane includes: a conductive polymer membrane including (a) a sulfonated poly(fluorinated arylene ether) and (b) a copolymer of vinylimidazole and 3-methacryloxypropylmethoxysilane in a weight ratio of 100:400 ~ 100:600; and a porous polytetrafluoroethylene membrane bonded to the conductive polymer membrane. The polymer composite electrolyte membrane is doped with phosphoric acids. |
