ELECTROLYTE MATERIAL, LIQUID COMPOSITION, AND MEMBRANE ELECTRODE ASSEMBLY FOR SOLID POLYMER FUEL CELLS

WIPO Patent Application WO/2011/013577

A1

Provided is a membrane electrode assembly which exhibits excellent power generation performance even under low, high or no humidity conditions. Also provided is an electrolyte material which has a low moisture content, and is suitable for use in the catalyst layer of a membrane electrode assembly. The electrolyte material comprises a polymer (H) obtained from a polymer (F) having an intrinsic viscosity of 0.3dL/g or more, a repeating unit (A) derived from a perfluoro monomer, which has an ion exchange group precursor and a five-membered ring to which said precursor group is bonded, and a repeating unit (B) represented by formula (u2), by converting the precursors into ion exchange groups. In the formula, R1 to R4 represent a fluorine atom or a C1-6 perfluoroalkyl group.
