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.
本发明公开了一种用于生产燃料电池电解质膜的方法,其特征在于在不使用光聚合
引发剂的情况下,通过紫外线照射
树脂后使可辐射聚合单体与
树脂接触,从而将可辐射聚合单体接枝聚合到
树脂上。通过紫外线辐照接枝聚合法获得的燃料电池电解质膜具有优异的抗氧化性和机械特性。通过使用这种电解质膜,可以获得性能极高的燃料电池。
