Figure S3: ORR polarization curves of the unmodified and N-doped Pt/C catalysts obtained in the GDE half-cell (data collected at room temperature in 2 M HClO4 in oxygen atmosphere) before and after thermodynamic and kinetic correction for MEA conditions (80 °C, 100 %RH). A) I/C ratio = 0.1 B) I/C ratio = 0.5 C) I/C ratio = 1.7.
