摘　　要：提高质子交换膜燃料电池(PEMFC)的工作温度,不但可以解决催化剂易受CO毒化、水热管理复杂等问题,还可以提高质子交换膜燃料电池的能量转化效率,是当今燃料电池发展的主要方向。在众多高温质子交换膜材料中磷酸掺杂的聚苯并咪唑(PBI)膜最具发展前景。综述了PBI基高温质子交换膜的发展状况,对比分析了不同PBI基质子交换膜的性能,展望了PBI基质子交换膜的发展前景。Enhancing PEMFC（polymer electrolyte membrane fuel cells）operation temperature is a solution to some issues which restrict development of PEMFC,including complex water and heat management,CO poisoning and lower energy-shift efficiency,thus HT-PEMFC（high temperature PEMFC）is becoming the main focus in fuel cell development.Amongst the various polymer matrix candidates,phosphoric acid-doped polybenzimidazole（PBI）seems so far the most promising in the field.The advance in the high temperature polymer electrolyte membranes based on PBI was reviewed.The properties of PBI based PEM（polymer electrolyte membrane）were compared.The overview of the development prospect of PBI based PEM was gave.
