Abstract FeNC catalysts are promising substitutes of platinum‐type catalysts for the oxygen reduction reaction (ORR). While previous research disclosed that high pyrolysis temperatures are required to achieve good stability, it was identified that

Today, state of the catalysts in proton exchange fuel cells are platinum-based. Cost estimates show that basically the catalyst is one of the most expensive components in the FC stack. While platinum is very active for the hydrogen oxidation reaction
