| Proton Exchange Membrane fuel cells (PEMFCs) are essential for the efficient operation of hydrogen-powered automobiles. To improve their performance, researchers have proposed tapered flow channels as a possible solution. However, determining the optimal value for the tapering has not been explored in depth. In this study, a numerical investigation was conducted to optimize the tapering of tapered serpentine channels in PEMFCs. The results show that while anode channel tapering has a negligible effect on performance, cathode channel tapering has a significant impact. The study found that a flow channel geometry with an inlet of 0.8 mm and an outlet of 0.2 mm, with a gradual decrease in cross-section, resulted in the maximum net output, with a 10.64% increase in net power output at 0.7 V. Additionally, the improved water management performance was observed. Based on these findings, tapering flow channels only on the cathode side could be utilized as an optimal design for achieving higher performance. Overall, this study is significant as it provides valuable insights into optimizing the performance of PEMFCs, which can enhance their efficiency and utilization in hydrogen-powered vehicles. It highlights the importance of investigating the effects of flow channel geometry on performance and can guide future research in this area to improve the efficiency of PEMFCs. | ||
