Fuel cells are a key technology for fossil-free long-haul mobility, and their optimisation includes understanding and minimising degradation mechanisms that directly affect the cell lifetime. Among the possible degradations occurring in Proton Exchange Membrane Fuel Cells (PEMFCs), cathode carbon corrosion is associated with startup and shutdown (SU/SD) events, but thanks to the implemented mitigation strategies, it is often considered marginal during operation.
