Carbon Corrosion in Fuel Cells-Fundamentals and Mitigation Approachesalysts. However, carbon is not thermodynamically stable under the operating conditions in PEMFCs, and the electrochemical oxidation of carbon is accelerated at elevated temperature and potential. The performance degradation is mainly caused by Pt detaching or agglomerating due to the weakened intera
