Title:
固体高分子電解質膜、その製造方法、燃料電池用膜電極接合体、及び燃料電池
Document Type and Number:
Japanese Patent JP5326288
Kind Code:
B2
Abstract:
A solid polymer electrolyte membrane is manufactured by applying radiation to a fluororesin or hydrocarbon-based resin and co-graft polymerizing at least a-methylstyrene and alkoxysilane containing styryl groups with said resin, and then sulfonating. The solid polymer electrolyte membrane of the present invention has excellent oxidation resistance. Said electrolyte membrane is placed between the fuel electrode and the air electrode of a fuel cell to form a fuel cell membrane electrode assembly. A fuel cell with extremely high performance can be produced by using said assembly in the fuel cell.
