Research progress on model for proton exchange membrane fuel cell Ⅱ Models of the whole PEMFC mechanism

数学模型是分析和优化燃料电池性能的有用工具,质子交换膜燃料电池(PEMFC)的模型研究是其技术发展和创新中必不可少的重要工作。对全面描述PEMFC机理模型的研究情况进行了综述,分别介绍了描述燃料电池的一维、二维和三维模型,分析和讨论了传质、传热和电化学反应过程及其对电池性能的影响,特别是水和热管理与传质限制,最后提出了在这些模型研究中须要解决的一些问题。

Mathematical models are useful for the analysis and optimization of the performance of fuel cells,and modeling studies are necessary for technology development and innovation of the proton exchange membrane fuel cells(PEMFC). The mechanistic models for the whole PEMFC are reviewed. One-dimensional models,two-dimensional models and three-dimensional models are introduced respectively. The process of mass transfer,heat transfer and electrochemical action,as well as its influence on the performance of PEMFC are analyzed and discussed, with particular emphasis on water and heat management and mass transfer limitations. Some questions to solve in the modeling researches are put forward.
