Synthesis of N and S co-doped porous carbon (DPC) in simple one-pot technique. High surface area DPC shows comparable activity for ORR in half-cell acidic PEMFC study. Real-world performance of DPC gives 20 mW/cm2 peak power density at 60 °C. Homogeneous Pt nanoparticles decorated DPC (Pt/DPC) outperforms commercial Pt/C. Pt/DPC shows maximum power density of 718 mW/cm2 with lower 0.3 mg/cm2 total Pt loading.
