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.
