Abstract

This review article provides an overview of the latest developments in polymer electrolytes, the ion conducting membrane and ionomeric binder, specially tailored for high temperature polymer electrolyte membrane fuel cells that operate at temperatures exceeding 100 °C without the assistance of humidification. This particular type of fuel cell have the added advantages of high CO tolerance, enhanced catalytic activity, and system simplification. While high temperature polymer electrolyte membrane fuel cells utilizing phosphoric acid-doped polybenzimidazole membranes have been extensively investigated and commercialized over the past half century, recent developments in alternative polymeric materials and their synergistic integration with newly applied ionomeric materials have been introduced, warranting a closer look at the chemistry and properties of such materials in conjunction with those developed previously. General background in high temperature polymer electrolyte membrane fuel cells, and as well as developments in various classification of membranes, ionomers, concluding with future challenges and outlook on high temperature polymer electrolyte membrane and ionomer technology is addressed from the vantage point of the membrane electrode assembly.

摘要

这篇评论文章概述了聚合物电解质、离子导电膜和离聚物粘合剂的最新发展，这些材料专为在超过 100 °C 的温度下运行而无需加湿的高温聚合物电解质膜燃料电池量身定制。这种特殊类型的燃料电池具有高 CO 耐受性、增强的催化活性和系统简化等额外优势。虽然利用磷酸掺杂的聚苯并咪唑膜的高温聚合物电解质膜燃料电池在过去的半个世纪中得到了广泛的研究和商业化，但引入了替代聚合物材料的最新发展及其与新应用的离聚物材料的协同整合，需要结合之前开发的材料，仔细研究此类材料的化学和特性。高温聚合物电解质膜燃料电池的一般背景，以及膜、离聚物的各种分类的发展，总结了高温聚合物电解质膜和离聚物技术的未来挑战和展望，从膜电极组件的角度出发.
