PROTON CONDUCTIVE MATERIAL, METHOD FOR MANUFACTURING PROTON CONDUCTIVE MATERIAL, AND MEMBRANE-ELECTRODE ASSEMBLY CONTAINING PROTON CONDUCTIVE MATERIAL

摘要

A proton conductive material in which hollow inorganic fine particles that have through holes on a surface of the hollow inorganic fine particles, that are filled with an electrolyte resin. In addition, a membrane-electrode assembly which has an anode electrode provided on one surface side of a solid polymer electrolyte membrane and including an anode catalyst layer, and a cathode electrode provided on the other surface side of the solid polymer electrolyte membrane and including a cathode catalyst layer, wherein at least the anode catalyst layer from among the pair of catalyst layers includes the proton conductive material.
