Water transport in polymer electrolyte membrane fuel cell: Degradation effect of gas diffusion layer

Summary Proton exchange membrane fuel cells (PEMFCs) have garnered considerable attention for transportation applications owing to their high energy efficiency. Understanding their long‐term durability is essential because the performance deteriorates over time. The water transport characteristics o...
