高温质子交换膜燃料电池由于有望克服散热效率低、环境适应性差(CO耐受性)等技术障碍,成为当今燃料电池发展的主要方向。然而,高温PEMFCs面临的技术挑战之一就是选择能够在高温下运行的质子交换膜材料。结合最近的文献报道,综述了高温质子交换膜的研究现状,分析了高温质子交换膜的发展前景。
Abstract：Proton exchange membrane fuel cell (PEMFC) using hydrogen as fuels is considered as one of promising clean energy sources due to its high efficency and zero-pollution. Moreover, some technical "bottlenecks" of current PEMFC technique can be surmounted once high temperature applied. However, one of the challenges for high temperature PEMFC is the selection of materials for proton exchange membranes. Currently, studies on proton exchange membrane mainly focus on three directions: replacing water with other non-aqueous solvent; synthesis of new polymeric materials containing proton conductive groups; and modifications made to perfluorosulfonated polymers. In this paper, recent development of proton exchange membranes based on above three directions was reviewed.
