【摘要】 根据流体动力学和传热学理论,建立了一个三维的单流道质子交换膜燃料电池模型,并应用有限控制体法对模型进行求解.总体而言,单流道燃料电池温差很小,阳极催化层温差大致在1 K左右,而阴极催化层温差小于3 K,最高温度发生在阴极催化层的反应区.将模拟的结果与有关的试验结果做了比较,结论相一致.更多还原

【Abstract】 A three-dimensional model on a single channel in proton exchange membrane fuel cell is created,based on the theory of fluid dynamics and heat transfer,and is solved by means of the control volume methods.In general,the temperature difference in a single channel of the fuel cell is very small.The difference of temperature is about 1K in the catalyst layer of the anode and less than 3K in that of the cathode.The maximum temperature emerges in the reaction zone of the cathodal catalyst layer.The results are compared with the experiment data in the conferences,and agree well with them.更多还原
