本文在考虑水-气界面条件的基础上，建立了质子交换膜燃料电池（PEMFC

In this paper, based on the consideration of the water-gas interface conditions, the condensation rate model of the proton exchange membrane fuel cell (PEMFC) is established to manage the water content of the gas diffusion layer. This model is also applied to a new type of flow field plate, which not only simulates fluid flow and convective coupling heat transfer under different conditions, but also the diffusion layer of liquid water migration and diffusion and the convection diffusion channel in the flow. Finally, a fuel cell test system was built and tested under different conditions. Compare with theoretical calculations.

本文在考虑水-气界面条件的基础上，建立了质子交换膜燃料电池（PEMFC）的凝结率模型，对气体扩散层的水含量进行管理。此模型还应用在一种新型的流场板上，不仅模拟不同条件下的流体流动和对流耦合传热，而且对液态水迁移和扩散的扩散层以及流中的对流扩散通道。最后，搭建一个燃料电池测试系统并在不同条件下进行了测试。结合理论计算进行对比。
