摘      要：Temperature is a crucial factor that is intrinsically related to fuel cell performances and categorizes the proton exchange membranes(PEM)into high and low temperature(HT,LT)types.With water as proton conductor,working temperature of LT-PEM is limited below 100℃.PEM fuel cell with an elevated temperature(HT-PEMFC,120℃)thus attracts much research attention on account of the significant benefits,such as simpler water management,faster electrode kinetics,improved CO tolerance of platinum catalyst,and heat recovery.As a well-known concept,numerous polymer membranes with doping phosphoric acid(PA)have been investigated for HT-PEMFC.In this review,the development trend for the most advanced technology of HT-PEM polybenzimidazole(PBI)membrane,other hydrocarbon-based membrane,and fluorinated membrane produced via pre-irradiation induced grafting with respect to their synthesis,properties,critical issues,and corresponding solutions is presented.
