摘要
质子交换膜燃料电池(proton exchange membrane fuel cells,PEMFCs)因其功率密度高、体积质量小、运行安全可靠和环境友好等优点而备受重视,在便携式设备、交通运输以及固定装置等领域具有重要应用前景.质子交换膜(proton exchange membranes,PEMs)作为核心部件,对PEMFCs的综合性能和操作灵活性起到了直接的影响.然而,目前常规的两种PEMs(以磺酸型水基和芳杂环型磷酸基电解质为代表)仅能在各自有限的温度和湿度(relative humidity,RH)范围内使用(80~90℃/100%RH、120~200℃/0%RH),仍存在诸多技术壁垒需要克服,制约了PEMFCs的商业化发展.本文将结合近年来国内外研究进展,以关键性科学问题为导向,梳理并归纳了宽温域质子交换膜的构建策略与优化思路,并对未来的发展方向与趋势做出展望.
Proton exchange membrane fuel cells(PEMFCs)have garnered significant attention in diverse fields,including portable devices,transportation,and fixed installations,owing to their notable features such as high-power density,compact size,reliable safety,and environmental friendliness.The performance and operational flexibility of PEMFCs systems heavily rely on the proton exchange membranes(PEMs),which serve as a critical component.However,conventional PEMs based on perfluorosulfonic acid and phosphoric acid doped polymer electrolytes are constrained by their limited operating temperature and relative humidity(RH)ranges(80-90℃/100%RH、120-200℃/0%RH).Consequently,these restrictions have hindered the commercialization of PEMFCs.This comprehensive review provides an overview of key scientific issues and recent research advancements,with a primary focus on the design strategies and optimization approaches for wide-temperature-range PEMs.Furthermore,it outlines future development prospects and emerging trends in this field.
