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。
Increasing the working temperature of PEMFC can not only solve the problem of catalyst being susceptible to CO poisoning and complex hydrothermal management, but also improve the energy conversion efficiency of proton exchange membrane fuel cells, which is the main direction for the development of fuel cells today . Phosphorus acid doped polybenzimidazole (PBI) membranes have the most promising applications in many high temperature proton exchange membrane materials. The development of PBI-based high-temperature proton exchange membranes was reviewed. The performance of different PBI-based proton exchange membranes was compared and the development prospect of PBI-based proton exchange membranes was prospected.
