The research progress of sulfonated polysulfone proton exchange membrane for fuel cells

Polysulfone is one of the most promising materials used in proton exchange membrane fuel cells. The recent research progress about the preparation of sulfonated polysulfone, the properties of sulfonated polysulfone membrane and cross-linked sulfonated polysulfone membrane are generalized and analyzed in detail. The hydrating capacity and the conductivity of the membrane are especially formulized to give the concrete information about the physical and electrochemical properties of the membrane. Some problems in the research and the research prospects are also discussed.
