建立高温质子交换膜燃料电池的机理模型可以加深对其内部传递现象和反应机理的认识,同时可以预测不同参数下燃料电池的性能,对优化电池的操作条件和结构参数等具有重要的指导意义。对现有的高温质子交换膜燃料电池机理模型进行了评述,分析了基于磷酸掺杂聚苯并咪唑膜(H3PO4/PBI)不同维数的稳态和动态模型及基于其他复合膜模型的优点和不足,并指出了高温质子交换膜燃料电池模型的研究方向。

Developing mechanism model for high-temperature proton exchange membrane fuel cell can help us to understand the transfer phenomena and reaction mechanism, to predict the performance of fuel cells under different parameters and optimize the operational condition and structure parameters of fuel cells. In this paper, different types of mathematical models for high-temperature proton exchange membrane fuel cell were compared and analyzed. The advantages and disadvantages of various models of different dimensional steady-state and dynamic models using phosphoric acid-doped polybenzimidazole membrane （PBI/H3PO4） and other membranes were analyzed. Finally, the research direction of the HT-PEMFC model was pointed out.
