Process for producing polymer electrolyte membranes for fuel cells, polymer electrolyte membranes for fuel cells produced by the process, and fuel cell membrane-electrode assemblies using the membranes
By performing photograft polymerization of functional monomers such that grafted chains will be introduced from the surface of a polymer base film into its interior without deteriorating its inherent characteristics and also by creating a multiplex crosslinked structure between the grafted chains and the base film under such conditions as to cause preferential radiation-induced crosslinking reaction, there is produced a polymer electrolyte membrane having high enough oxidation resistance and proton conductivity to be suitable for use in fuel cells.
