Popular Summary To advance the development and accessibility of fuel cells, long-lasting, affordable materials with high electrocatalytic activity for the oxygen reduction reaction (ORR) should be developed. Here, the authors present a precious-metal-free ORR catalyst prepared using a simple procedure and low-cost precursors. The Fe-N-C catalyst, derived from an Fe-porphyrinic framework, has performance that competes with other platinum group metal free catalysts.
