POLYMER ELECTROLYTE MATERIAL, POLYMER ELECTROLYTE COMPONENT USING THE SAME, MEMBRANE ELECTRODE ASSEMBLY AND POLYMER ELECTROLYTE TYPE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To obtain a polymer electrolyte material satisfying both high proton conductivity and low-fuel crossover, has excellent hot water resistance and durability and achieves a high output and high energy density when made into a polymer electrolyte fuel cell, a polymer electrolyte membrane comprising the same, a membrane electrode assembly and a polymer electrolyte type fuel cell.

SOLUTION: The polymer electrolyte material comprises a polymer having at least a constituent unit represented by a specific structural formula as a component (A) and a constituent unit represented by a specific structural formula as a component (B). The polymer contains an ionic group. The polymer electrolyte component, the membrane electrode assembly and the polymer electrolyte fuel cell are each constituted by using the polymer electrolyte material.
