Abstract: Disclosed is a polymer electrolyte membrane for a fuel cell that has a high ionic conductivity even at a high temperature without humidification. The polymer electrolyte membrane comprises a film composed of a polyimide copolymer containing phenylbenzimidazole, and an acid impregnated within the polyimide copolymer film. Also disclosed is another polymer electrolyte membrane for a fuel cell that has good chemical resistance and improved physical properties when compared to those of the previous polymer electrolyte membrane.
