Proton exchange membrane fuel cell, or polymer electrolyte fuel cell, (PEMFC) has received a significant amount of attention for green energy applications due to its low carbon emission and less other toxic pollution capacity. Herein, we develop a three-dimensional (3D) computational fluid dynamic model. The values of temperature, pressure, relative humidity, exchange coefficient, reference current density (RCD), and porosity values of the gas diffusion layer (GDL) were taken from the published literature. The results demonstrate that the performance of the cell is improved by modifying temperature and operating pressure. Current density is shown to degrade with the rising temperature as explored in this study. The findings show that at 353 K, the current density decreases by 28% compared to that at 323 K. In contrast, studies have shown that totally humidified gas passing through the gas channel results in a 10% higher current density yield, and that an evaluation of a 19% higher RCD value results in a similar current density yield.
质子交换膜燃料电池，或聚合物电解质燃料电池（PEMFC），因其低碳排放和较少的其他有毒污染能力，在绿色能源应用方面受到了广泛关注。在此，我们开发了一个三维（3D）计算流体动力学模型。温度、压力、相对湿度、交换系数、参考电流密度（RCD）以及气体扩散层（GDL）的孔隙率值均取自已发表的文献。结果表明，通过改变温度和工作压力可提高电池性能。本研究发现，电流密度会随着温度升高而降低。研究结果显示，在353 K时，电流密度相较于323 K时降低了28%。相比之下，研究表明，完全加湿的气体通过气体通道可使电流密度产率提高10%，而对RCD值提高19%进行评估时，会得到类似的电流密度产率。
