摘要

本研究采用多尺度多相PEMFC模型模拟了三种不同阴极流场设计的电池性能，包括常规(矩形、梯形)和孔口型流场设计。结果表明，孔型流场设计使氧气浓度分布均匀，保证了氧气向出口的有效供应。此外，在2.0A/cm²的高电流密度下，与传统流场设计相比，孔型设计降低了浓度损失，提高了性能。

Enhancing PEMFC Performance through Orifice-shaped Cathode Flow Field Designs

This study applied a multiscale, multiphase PEMFC model to simulate the cell performance for three different cathode flow field designs, including conventional(rectangular, trapezoidal), and orifice-shaped flow field designs. The results demonstrated that the orifice-shaped flow field designs allowed for uniform distribution of oxygen concentration, ensuring its efficient supply to the outlet. Also, at a high current density of 2.0A/cm², the orifice-shaped design exhibited reduced concentration losses and improved performance compared to conventional flow field designs.
