POLYMER ELECTROLYTE COMPOSITION, POLYMER ELECTROLYTE MOLDING, AND POLYMER ELECTROLYTE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a polymer electrolyte composition excellent in protonic conductivity under a low moisture condition, excellent in mechanical properties and chemical stability, and capable of achieving long-term physical and chemical durability when made into a polymer electrolyte fuel cell; and to provide a polymer electrolyte molding and a polymer electrolyte fuel cell using the same.

SOLUTION: The polymer electrolyte composition is a copolymer having one or more each of a segment (S1) containing an ionic group and a segment (S2) containing no ionic group, wherein the segment (S1) containing an ionic group and the segment (S2) containing no ionic group have each a structural unit represented by a specific structure. The polymer electrolyte composition, a polymer electrolyte molding and the polymer electrolyte fuel cell are constituted by using the polymer electrolyte composition.
