초록

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.
