Thermal modeling of proton exchange membrane fuel cell

介绍了质子交换膜燃料电池(PEMFC)的热问题模拟现状,根据研究问题的需要,对模拟相关的模型进行了描述,并应用计算机模拟技术对质子交换膜燃料电池进行了热模拟。从热源、温度场在质子交换膜燃料电池内部的分布情况以及电池性能等方面进行了分析和讨论,得出了结论:热源、温度在质子交换膜电池内部分布的不均匀性和不同电流密度情况下膜电极组件的温差。电池性能曲线与试验结果进行了比较,模拟与试验结果基本吻合。

The thermal modeling of proton exchange membrane fuel cell in present was introduced, and the model related to simulation in the study was described in the article. The thermal modeling of proton exchange membrane fuel cell was done and its data was analyzed and discussed in the distribution of thermal sources and temperature fields,the performance of fuel cell. The results show that distributions of thermal sources and temperature are uneven in proton exchange membrane fuel celt, and temperature differences based on different current density exist in membrane electrode assemble. The performance curve of the cell is compared with the experiment data, and agrees well with them.
