SOLID POLYMER ELECTROLYTE MEMBRANE, MEMBRANE-ELECTRODE CONJUGANT, FUEL CELL, WATER ELECTROLYSIS CELL AND WATER ELECTROLYTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a solid polymer electrolyte membrane excellent in power generation performance.SOLUTION: A solid polymer electrolyte membrane contains (A) hollow particles of which porosity is 20-90 volume %, and (B) a polymer containing ion exchange group. It preferably contains the hollow particles (A) by 0.1-20 parts relative to the polymer (B) 100 parts. It is further preferred that the hollow particles (A) contain a crosslinked polymer. Further, the crosslinked polymer is such a crosslinked polymer which is obtained by polymerizing using a cross-linking vinyl monomer.SELECTED DRAWING: None
