METHOD FOR PRODUCING POLYMER ELECTROLYTE MEMBRANE, POLYMER ELECTROLYTE MEMBRANE AND DIRECT METHANOL FUEL CELL |
摘要 |
Disclosed is a method for producing a polymer electrolyte membrane, which comprises a step for modifying a polymer electrolyte membrane, which is substituted with multivalent cations to have a salt form, by subjecting the membrane to a modification process selected from heating, active-energy ray irradiation and electrical discharge. Preferably, this method for producing a polymer electrolyte membrane may also comprise a step for processing the thus-modified polymer electrolyte membrane with an acid. By this method, there can be obtained a polymer electrolyte membrane having high methanol barrier property and proton conductivity. ® KIPO & WIPO 2009 |
