REINFORCED ELECTROLYTE MEMBRANE FOR FUEL CELL, METHOD FOR PRODUCTION THEREOF, MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL, AND SOLID POLYMER-TYPE FUEL CELL HAVING THE ASSEMBLY

摘要

A reinforced electrolyte membrane for a fuel cell wherein the electrolyte membrane is reinforced with a porous membrane and a radical scavenger is immobilized in the porous membrane. The reinforced electrolyte membrane for a fuel cell is a solid polymer electrolyte membrane suppressing the radical scavenger from leaking outside of the system and having good chemical durability.
