Abstract
Disclosed is a method for producing an electrolyte membrane for fuel cells, which is characterized in that a radically polymerizable monomer is graft-polymerized to a resin without using a photopolymerization initiator by bringing the radically polymerizable monomer into contact with the resin after irradiating the resin with ultraviolet light. The electrolyte membrane for fuel cells obtained by ultraviolet irradiation graft polymerization has both excellent oxidation resistance and excellent mechanical characteristics. By using such an electrolyte membrane, there can be obtained a fuel cell exhibiting extremely high performance.
