摘要：
The present invention relates to a thermostable polymer electrolyte membrane which comprises a main chain comprising an alicyclic polybenzimidazole and a graft chain added to the main chain by radiation-induced graft polymerization, wherein at least a part of the graft chain has sulfonic acid groups. The thermostable polymer electrolyte membrane of the invention is used for many apparatuses such as polymer electrolyte fuel cells or water electrolysis devices, in which the electrolyte membrane exhibits high proton conductivity, low fuel permeability, high oxidation resistance and superior mechanical property under operation conditions at high temperature. The present invention also provides a simple and low-cost process for producing the same.
