| Abstract: | The molecular structure and microstructure model of perfluorosulfonic acid ion-exchange membrane(PFSIEM) are described.Especially,"three-phase" structure,"sandwich" model and ion clusters net structure model of perfluorosulfonic acid ion-exchange resin(PFSIER) are discussed.The application and research progress of PFSIEM in the chlor-alkali electrolysis,direct methanol fuel cell(DMFC),proton exchanged membrane fuel cell(PEMFC),pervaporation,gas separation and photo-catalysis are reviewed in detail.The directions of the application and research of PFSIEM were suggested.Besides,the modification of PFSIEM,the development of new PFSIEM materials and the regeneration and reuse of disposable PFSIEM will be further investigated in the near future. |
