本文通过实验和仿真研究了不同流道形态对质子交换膜燃料电池（PEMFC）性能的影响。实验在元泽大学燃料电池中心进行，并采用三维全电池计算流体动力学模型进行了模拟。本研究采用的流道类型分别为均匀深度单路径的平行流道和阶梯深度4路径的蛇形流道。实验结果表明，采用蛇形流道的PEMFC的性能（即电池电压）优于采用平行流道的PEMFC，仿真模型准确地反映了这一点。对于平行流道，不同的流道深度对PEMFC的性能影响较大。然而，对于蛇形流道，这种影响不显著。此外，该模型的计算结果与实验数据吻合较好。这些验证表明，该仿真模型可以自信地补充从实验数据中无法获得的有用的局部信息。版权所有©2007 John Wiley & Sons， Ltd
Experiments and simulations are presented in this paper to investigate the effects of flow channel patterns on the performance of proton exchange membrane fuel cell (PEMFC). The experiments are conducted in the Fuel Cell Center of Yuan Ze University and the simulations are performed by way of a three‐dimensional full‐cell computational fluid dynamics model. The flow channel patterns adopted in this study include the parallel and serpentine flow channels with the single path of uniform depth and four paths of step‐wise depth, respectively. Experimental measurements show that the performance (i.e. cell voltage) of PEMFC with the serpentine flow channel is superior to that with the parallel flow channel, which is precisely captured by the present simulation model. For the parallel flow channel, different depth patterns of flow channel have a strong influence on the PEMFC performance. However, this effect is insignificant for the serpentine flow channel. In addition, the calculated results obtained by the present model show satisfactory agreement with the experimental data for the PEMFC performance under different flow channel patterns. These validations reveal that this simulation model can supplement the useful and localized information for the PEMFC with confidence, which cannot be obtained from the experimental data.
