摘　　要：质子交换膜燃料电池(PEMFCs)具有独特的能源转化和储存方式,因此引起了科学家广泛的研究兴趣.全氟磺酸质子交换膜(PFSA)是目前低温型PEMFCs(<100℃)中应用最为广泛的关键核心材料之一,在很大程度上决定着PEMFCs的性能优劣.提高工作温度可以赋予PEMFCs更高的转化效率、更快电极反应、更高的杂质耐受能力、更便捷的水热管理方式等,然而,质子交换膜(PEM)在高温下的传质性能衰减阻碍PEMFCs的高温应用.引入磷酸结构是目前改善PEM高温传质性能常用的策略.本文总结了近年来含磷酸结构全氟磺酸质子交换膜的研究进展,并讨论了引入磷酸结构后存在的问题,为后续的高温质子交换膜的研究工作提供指导作用.Proton exchange membrane fuel cells(PEMFCs)with unique energy conversion and storage have been received widespread attention.Perfluorosulfonic acid proton exchange membrane(PFSA)is one of the most widely used key core materials in low-temperature PEMFCs(<100℃)at present and largely determines the PEMFCs performance.Increasing the operating temperature can confer PEMFCs higher conversion efficiency,faster electrode response,higher impurity tolerance,more convenient hydrothermal management methods,etc.However,the degradation of mass transfer performance of proton exchange membrane(PEM)at high temperature hinders the high temperature application of PEMFCs.Incorporation phosphoric acid structure into membrane is a commonly used strategy to improve the high-temperature mass transfer performance of PEMs.This paper summarizes the progress of phosphoric acid contained perfluorinated proton exchange membranes in recent years and discusses the problems in phosphoric acid contained PEMs,which paves the guidance for the PEMs at high-temperature in related fields.
