Abstract

The encapsulation of the proton-exchange membrane fuel cell (PEMFC) is an essential step of fuel cell stack assembly. The selection of the assembly pressure is very important to the stack performance and life. Based on that, this paper presents a method to describe the internal physical deformation of the gas diffusion layer (GDL) after inhomogeneous pressure by using user-defined functions (UDFs). The results show that the transmission difference caused by the nonuniform GDL deformation can be clearly seen by the UDFs method, and there is an obvious transition of GDL at the interface of the channel and the rib. A three-dimensional single-channel PEMFC model is established, and an optimal assembly pressure range is obtained, between 1.5 and 2.0 MPa. The maximum thermal stress inside the cell occurs in the middle of the membrane electrode assembly and decreases as the assembly pressure increases. Furthermore, the influence of rib-channel ratios is discussed. Compared to the fuel cells with ratios of 2:1, 2:3, and 1:2, the one with 1:1 exhibits the maximum current density and the highest power density.

摘要

质子交换膜燃料电池（PEMFC）的封装是燃料电池堆组装的关键步骤。组装压力的选择对电池堆性能和寿命至关重要。基于此，本文提出了一种通过用户自定义函数（UDFs）来描述气体扩散层（GDL）在非均匀压力作用后的内部物理变形的方法。结果表明，通过UDFs方法可以清晰地看到由GDL不均匀变形引起的传输差异，并且在流道和肋片的界面处GDL存在明显的过渡。建立了三维单通道PEMFC模型，并获得了最佳组装压力范围为1.5至2.0MPa。电池内部的最大热应力出现在膜电极组件的中间，并随着组装压力的增加而减小。此外，还讨论了肋片-流道比的影响。与肋片-流道比为2:1、2:3和1:2的燃料电池相比，肋片-流道比为1:1的燃料电池具有最大电流密度和最高功率密度。
