| 摘要 |
The present invention provides for a solid polymer electrolyte membrane comprising a fluorinated ionomer having imbibed therein the polymerization product of a composition comprising a non-fluorinated, non-ionomeric monomer, wherein the fluorinated ionomer comprises at least 6 mole % of monomer units having a fluorinated pendant group with a terminal ionic group. Catalyst coated membranes and fuel cells using these membranes are also provided.
