Abstract: Provided is poly(benzimidazole-co-benzoxazole) having polybenzimidazole to which benzoxazole units are introduced, as a polymer electrolyte material. The polymer electrolyte material has both high proton conductivity and excellent mechanical properties even when it is obtained by in-situ phosphoric acid doping. The polymer electrolyte material may substitute for the conventional phosphoric acid-doped polybenzimidazole in a polymer electrolyte membrane fuel cell, particularly in a high-temperature polymer electrolyte membrane fuel cell.
