3、cal Engineering Research Center, East China University of Science andTechnology, Shanghai 200237, China)Abstract: The molecular structure and microstructure model of perfluorosulfonic acid ion- exchange membrane( PFSIEM) are described. Especially, / three- phase0 structure, / sandw ich0 model and io
4、n clusters net struc-ture model of perfluorosulfonic acid ion- exchange resin ( PFSIER) are discussed. The application and researchprogress of PFSIEM in the chlor - alkali electrolysis, direct methanol fuel cell ( DM FC) , proton exchangedmembrane fuel cell ( PEMFC) , pervaporation, gas separation a
5、nd photo- catalysis are reviewed in detail. Thedirections of the application and research of PFSIEM were suggested. Besides, the modification of PFSIEM , thedevelopment of new PFSIEM materials and the regeneration and reuse of disposable PFSIEM w ill be further in-vestigated in the near future.Key words: perfluorosulfonic acid; ion- exchange membrane; chlor- alkali electrolysis; fuel cells; pervapora-tion欢迎投稿欢迎订阅欢迎刊登广告# 74 # S / 25
