Polymer electrolyte membrane and polymer electrolyte fuel cell |
摘要 |
A polymer electrolyte membrane is provided which comprises a copolymer prepared by polymerization of a phosphorus-atom-containing unsaturated monomer comprising at least one phosphorus atom and at least one ethylenically unsaturated bond in a molecule, typically represented by the general formula (1):
and a monomer or prepolymer of a number-average molecular weight of 2,000 or more having an ethylenically unsaturated bond. Thereby, there are provided a polymer electrolyte membrane having both the high proton conductivity of the polymer electrolyte membrane containing phosphoric acid ester and a high mechanical strength, and a polymer electrolyte fuel cell using the polymer electrolyte membrane. |
