摘　　要：以Nafion为代表的全氟磺酸水化膜是目前聚合物电解质膜燃料电池(PEMFCs)中最常用的质子交换膜(PEM),但此类膜的质子导电性能强烈依赖于水,由水的冻结或蒸发会使其失去质子导电性能。离子液体具有接近零的蒸汽压、低熔点、较宽的电化学窗口,将离子液体引入PEM体系可望大大扩展PEM的工作温度范围,提高其电导率。文中对近年来离子液体在聚合物质子导电材料中的应用进行了综述,并对其研究发展前景作了展望。The perfluorinated sulfonic acid membranes like Nafion are the most widely used proton exchange membrane（PEM） for polymer electrolyte membrane fuel cells.However,the hydrated membranes may lose proton conductivity due to the freezing or evaporation of water.Ionic liquids have characteristics of low melting point,low vapor pressure,etc.With the introduction of ionic liquid,the range of the working temperature of PEM can be extended and the proton conductivity can be improved.In present work,the progress of application research of ionic liquids in proton conducting polymers was reviewed.The future development of this field was also prospected.
