| 摘 要： | 以蛇形流场质子交换膜燃料电池阴极为研究对象，取其中一部分建立三维、稳态的数学计算模型，利用CFD（计算流体动力学）方法研究了质子交换膜燃料电池阴极内的流动和传质过程，得到了阴极内氧气和水蒸气的质量分数的分布情况，探讨了流道宽度和深度对气体在催化层空间分布的影响，为燃料电池流场的设计和改进提供了参考依据。

| Abstract: | A three-dimensional model based on a section of serpentine flow field in the cathode of the proton exchange membrane fuel cell (PEMFC) was developed.Computational fluid dynamics (CFD) software was used to study the flow and transport of the components in the cathode layer of the PEMFC.The effect of channel width and depth of PEMFC flow field on gas distribution in the catalyst-layer was numerically studied.The numerical simulation results provided reference for how to design and improve the PEMFC flow field for achieving optimum oxygen distribution in the whole catalyst layer. |
