Fig. 4. — (A) LSV of all cells at 80°C and 100% RH sweeping potential from 0.15 to 0.6 V at a scan rate of 0.5 mV s⁻¹ and supplying hydrogen (0.1 slpm, anode) and nitrogen (0.1slpm, cathode). (B) Mass activity of Pt at 0.85 V under 80°C (100 and 30% RH), 100°C (53 and 30% RH), and 120°C (30% RH). IR-included polarization curves at 80°C and 100% RH (C), 100°C and 53% RH (D), 100°C and 30% RH (E), and 120°C and 30% RH (F). For the mass activity and IR-included polarization curves, the catalyst loading was 0.5 mg cm⁻² for all electrodes supplying hydrogen and air to the anode and cathode, respectively, with no back pressure.
