[Display omitted] •ORR performance of FePc is greatly improved by anion-exchange ionomer in acidic medium.•Anion-exchange ionomer can increase local pH of electrode/electrolyte interface.•The increase in interface pH was verified by in situ Raman technology. Iron–nitrogen doped carbon (Fe/N/C) elect...
