ELECTROLYTE MATERIAL, LIQUID COMPOSITION, AND MEMBRANE ELECTRODE ASSEMBLY FOR SOLID POLYMER FUEL CELLS |
摘要 |
It is to provide a membrane/electrode assembly excellent in the power generation characteristics under low or no humidity conditions and under high humidity conditions; and an electrolyte material having a low water content, suitable for a catalyst layer of a membrane/electrode assembly. It is to use an electrolyte material, which comprises a polymer (H) having ion exchange groups converted from precursor groups in a polymer (F), the polymer (F) having repeating units (A) based on a perfluoromonomer having a precursor group of an ion exchange group and a 5-membered ring to which the precursor group is bonded and repeating units (B) represented by the formula (u2), and having an intrinsic viscosity of at least 2.3 dL/g.
wherein R 1 to R 4 are a fluorine atom, a C 1-6 perfluoroalkyl group or the like. |
