Fuel cells are compact energy conversion units that utilize clean energy sources like hydrogen and convert them into electricity through a series of oxidation–reduction reactions. Specifically, proton exchange membrane fuel cells (PEMFCs), an integral part of electric vehicles, utilize proton-conductive membranes for operation. Unfortunately, these membranes suffer from a trade-off between high durability and high…
