Development of study on novel proton exchange membranes for fuel cell

Proton exchange membrane fuel cells(PEMFC)have attracted considerable attention since they offer numerous benefits,such as high power density,low or zero emission,high efficiency and reliability.Nafion membrane,a perfluorosulfonate ionomer,is the major membrane used in PEMFC at present.But Nafion membrane is very expensive and also presents high water drag,which adds difficulty to the water management of a fuel cell system.In addition,Nafion membrane is a poor barrier to methanol crossover.So,finding better and cheaper proton exchange membranes has been being an important part of fuel cell research in the past decade.The development of novel proton exchang membranes in recent years,including perfluorinated membranes,partially fluorinated membranes and nonfluorinated membranes,is reviewed in this article.
