Partially sulfonated polybenzimidazole based polymer, method for preparing the same, MEA for fuel cell using the polybenzimidazole based polymer and method for preparing the same

A partially sulfonated polybenzimidazole based polymer for fuel cell membrane is prepared by copolymerizing monomers of 3,3′-diaminobenzidine, isophthalic acid and 5-sulfoisophthalic acid to obtain a partially sulfonated polybenzimidazole, and doping the partially sulfonated polybenzimidazole with i...
