摘　　要：质子交换膜是质子膜燃料电池的核心材料,它主要起到隔离燃料和氧气、传递质子、附着催化剂等作用,是决定质子膜燃料电池工作时间的主要因素。含有膦酰基团的聚合物在高温低湿条件下能够发生自电离,具有较高的质子传导能力和较好的机械性能,作为质子交换膜具有长服役时间和高服役温度等特点,含膦酰基团的高分子材料有望成为质子交换膜材料最具前景的候选材料之一。笔者对由膦酰单体直接聚合的膦酰化高分子材料的合成、性能进行了系统的阐述与总结。Proton exchange membrane is the key material for proton exchange membrane fuel ceils, which played an important role in isolating the fuel gas and oxygen, transferring protons, adhering catalyst and so on. It is the main factor to determine the lifetime. The polymer containing phosphate moiety can self-dissociate in high-temperature and low humidity even in the anhydrous state, it has higher proton transfer function and good mechanical properties, it maybe have longer service time and higher service temperatures. So proton exchange membrane materials with phosphonic acid are one of the most promising candidate materials. The methods for the preparation and performance of polymer containing phosphonic group were described and summarized in this paper.
