摘要
基于磷酸掺杂聚苯并咪唑(PBI)高温膜燃料电池(HT-PEMFC)具有环境耐受性好、水热管理简单等优点,被认为是未来PEMFC发展的方向。作为HT-PEMFC的核心组件,膜电极对其性能、成本和寿命有着决定性影响。由于高温体系中磷酸电解质的存在,HT-PEMFC膜电极组分和特性与低温膜(如Nafion)燃料电池大不相同,同时还存在着铂用量高、磷酸流失以及高温带来的材料稳定性问题。本文综述了HT-PEMFC膜电极的构建、组分和结构优化方面的研究工作,概述了目前HT-PEMFC膜电极的研究趋势并展望了其未来发展方向,以期对后续先进HT-PEMFC膜电极研究开发提供有益借鉴。
High temperature polymer electrolyte membrane fuel cell(HT-PEMFC) based on phosphoric acid(PA)-doped polybenzimidazole(PBI) is considered as the trend of PEMFC future development due to its good environmental tolerance and simplified water/thermal management. As the key component of HT-PEMFC, membrane electrode assembly(MEA) plays an important role in determining its performance, cost and durability. Due to the presence of PA electrolyte, the composition and characteristics of the MEAs for HT-PEMFC are quite different from those for the PEMFC based on low temperature membranes(e.g. Nafion). At the same time, high use amount of Pt catalyst, PA loss and materials instabilities at high temperatures are concerns that HT-PEMFC currently confronts. In this paper, the studies on the construction, composition and structure optimization of HT-PEMFC MEA are reviewed, the research trend is summarized, and its future development is prospected, in the hope of providing useful guidance for the R&D of advanced HT-PEMFC MEAs in the future.
