ELECTROLYTE MEMBRANE COMPOSITION, SOLID POLYMER ELECTROLYTE MEMBRANE, METHOD OF PRODUCING SAID ELECTROLYTE MEMBRANE, MEMBRANE-ELECTRODE ASSEMBLY, SOLID POLYMER-TYPE FUEL CELL, AND WATER ELECTROLYSIS CELL AND WATER ELECTROLYSIS APPARATUS

摘要

The present invention relates to an electrolyte membrane composition, solid polymer electrolyte membrane, method of producing said electrolyte membrane, membrane-electrode assembly, solid polymer-type fuel cell, water electrolysis cell, and water electrolysis apparatus. This electrolyte membrane composition comprises a polymer (A) that has an ion exchange group, and a polymer (B) that has an arylene sulfide backbone and is soluble in an organic solvent.
