The gas flow field significantly impacts the output power of proton exchange membrane fuel cells (PEMFCs). A nonuniform design is developed in this study to optimize arrangement blocks field, thereby enhancing PEMFC power. Numerical simulations indicate block arrangements mass transfer performance compared uniform arrangements. Under 0.4 V working voltage, new has increased density by 4.84%. with three positioned near outlet effectively leverages entrance effect and disrupts thicker boundary layer. This improvement increases reactant concentration catalyst layer, reaction process. efficiency liquid water transport also been enhanced outlet, helping mitigate flooding. impact varying quantities on resistance assessed through pumping cathode. Results that for same number blocks, remains identical both fields. With rear arrangement, increasing raises As count from 3 7, as much 64.7%. However, change current not significant. Therefore, adopting a simple yet effective strategy enhance performance.
