To tackle performance issues stemming from assembly errors in practical fuel cell applications, a criss-crossed matching design for anode and cathode bipolar plates (BPP) is proposed. The effectiveness of the proposed design is assessed by joint simulations of finite element analysis (FEA) and computational fluid dynamics (CFD). Concurrently, the orthogonal experimental method is utilized to investigate the performance of the criss-crossed matching design at various operating conditions. The results show that the GDL deformation rate of the criss-crossed matching design with error in practical assembly is merely 4.8%, significantly lower than the 19.9% observed in the aligned matching design. Furthermore, the criss-crossed design performance could be improved by 5.9% compared to the aligned matching design in practical assembly with error. The criss-crossed matching design consistently outperforms the aligned matching design at various operating conditions. Notably, the highest performance growth rate, observed in high stoichiometric ratio and high humidity, reaches 12.38%.

考虑不可避免的装配误差的PEMFC双极板纵横交错的匹配设计

为了解决实际燃料电池应用中组装错误引起的性能问题，提出了一种阳极和阴极双极板（BPP）的十字交叉匹配设计。通过有限元分析 (FEA) 和计算流体动力学 (CFD) 的联合模拟来评估所提出设计的有效性。同时，利用正交实验方法来研究十字形匹配设计在各种操作条件下的性能。结果表明，实际装配中存在误差的纵横交错匹配设计的GDL变形率仅为4.8%，明显低于对齐匹配设计的19.9%。此外，在实际装配中，与有误差的对齐匹配设计相比，十字交叉设计性能可提高5.9%。在各种操作条件下，纵横交错的匹配设计始终优于对齐的匹配设计。值得注意的是，在高化学计量比和高湿度下观察到的最高性能增长率达到12.38%。
