摘要：
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 inorganic acid.
