摘要:

高温质子交换膜燃料电池(HT-PEMFCs)因其具有催化剂CO耐受性良好,能量转化率高,水热管理简单等优点,成为了能源领域重要的研究方向之一。高温质子交换膜(HTPEM)是它的主要部件之一,分别以水、磷酸分子和咪唑分子为质子传导载体分析了目前HTPEM的研究现状,比较后得出了以磷酸为质子载体的HTPEM性能最佳的结论,指出了研究中尚存的问题,并展望了未来HTPEM可能的研究方向。

Abstract:

High temperature proton exchange membrane fuel cells (HT-PEMFCs) have become one of the most important research directions in the energy field because of their good catalyst CO tolerance, high energy conversion rate, and simple hydrothermal management. High temperature proton exchange membranes (HTPEMs) are the most critical component. In this paper, we reviewed current research progress of HTPEM based on proton carriers at high temperature, including water, phosphoric acid and imidazole molecules. It appears that HTPEMs based on phosphoric acid doping perform the best. There are also a few issues that need to be addressed. Future directions concerning the development of HTPEMs were also outlined.

Key words: fuel cell, membrane, high temperature, proton exchange membrane, conductivity
