Polyaniline (PANI) and phosphoric acid (PA) doped sulfonated polybenzimidazole (SPBI) composite membrane was prepared for application in high-temperature proton exchange membrane (PEMFC) without the need of humidification. The synthesis and characterization of targed composite membrane were introduced in this paper.
