ABSTRACT:
A polymer electrolyte membrane, a method of manufacturing the same, and a fuel cell including the polymer electrolyte membrane are provided, wherein the polymer electrolyte forms an interpenetrating polymer network (IPN) of a polymer by simple blending of a hydrophobic polyimide having a reactive terminal group and a hydrophilic aromatic polymer having ion conductivity. The polymer electrolyte membrane has reduced swelling properties due to highly dense crosslinking of polyimide through the reactive terminal group, shows high ion conductivity at low humidity, and has methanol crossover suppressing ability. Accordingly, a fuel cell with improved electric and mechanical properties can be provided.
