Summary: This study investigates the influence of different properties of gas diffusion layers (GDLs) on the performance of a proton-exchange polymer electrolyte fuel cell (PEMFC). Three-dimensional numerical simulations were conducted to compare several commercial GDLs with varying properties. The results show that high electrical conductivity and permeability contribute to better fuel cell performance. Moreover, the absence of a microporous layer (MPL) can lead to membrane dehydration and cell degradation issues.

Summary: Renewable energy sources have made a significant contribution to global energy demand, but their intermittent nature can cause sustainability and efficiency issues. Proton exchange membrane fuel cells (PEMFCs) have emerged as an alternative system with longer lifespan, efficiency, and cost-effectiveness. However, their performance depends on operating conditions, requiring instant and proper control for maximizing efficiency and lifespan. This study utilizes a whale optimization algorithm (WOA)-based maximum power point tracking (MPPT) controller for a PEMFC system, showing accurate and fast MPPT performance, reduced power fluctuations, and increased production efficiency.
