The design of flow field has a significant impact on the performance proton exchange membrane fuel cells (PEMFCs). In this study, novel leaf bionic is designed and optimized based Murray's law. power consumption ratio first used in PEMFC. Additionally, an evaluation criterion, mass transfer efficiency criterion (MTEEC), proposed to characterize efficiency, synergy theory analyze differences among various fields. results demonstrate that adding multi-level channel obstacles significantly enhances cell output reduces voltage losses regions. Applying law distribute improves uniformity oxygen concentration distribution alleviates under-rib water accumulation. Compared secondary stream (SSFF), structure mesh (SMLBFF) demonstrates nearly 19% increase current density at 0.45 V. SMLBFF exhibits 81.51% convective rate compared SSFF 0.4 Moreover, MTEEC shows improvements 179.68% 0.5 A/cm2 135.43% 1.0 A/cm2, SSFF.

The use of proton exchange membrane fuel cells (PEMFCs) in sustainable energy applications depends on their high efficiency levels along with ability to produce low emissions and operation without noise. optimization PEMFC design variables faces difficulties because the complex nonlinear relationships which exist between activation overpotential concentration internal resistance. methods PSO, DE WOA face three major setbacks include delayed convergence rates as well sensitiveness initial parameter settings tendency lock onto sub-optimal solutions. study presents Parrot Optimizer (PO) a new metaheuristic algorithm derives its inspiration from adaptive behaviors Pyrrhura Molinae parrots overcome current challenges. PO serves optimize six stack for BCS 500 W, Nedstack 600 W PS6, SR-12 Horizon H-12, Ballard Mark V, STD 250 W. research performs an extensive comparison nine advanced algorithms analyze performance against DE, WOA, Rabbit Optimization Algorithm (ROA), Flamingo Herd (FHO), Arithmetic (AOA), Sine Cosine (SCA), Multi-Verse (MVO) Bat (BA). objective function Sum Squared Error (SSE) voltage is minimized using different comparative analysis. Simulation results I-V V-P characteristics aligned closely experimental data under varying temperature pressure conditions. achieved lowest Mean SSE values across all cases, 0.025519, 0.275211, 0.242413, 0.102915, 0.148632, 0.283774 stacks, respectively. Additionally, demonstrated fastest runtime (RT) 0.116855 s H-12 stack. indicate that delivers better than existing it reaches outputs every test scenario. characteristic simulations match proves theoretical value practical usage solving problems. demonstrates dependable method improves processes while enhancing operational reliability through future includes real-time control combination system scalability.
