From: Bicontinuous RuO2 nanoreactors for acidic water oxidation
Polarization curves, Tafel curves and Nyquist plots of MD-RuO2-BN, K-RuO2 and C-RuO2 (a–c). The high-frequency region of Nyquist plot is used to determine the solution resistance (about 9 Ω) for iR-correction. d Constant current stability testing for OER, no iR-correction. Schematic diagram of a typical PEMWE device (e) and the MEA components (f). Polarization curves (g) and time-dependent current density curves (h) of the PEM electrolyzer measured at 80 °C, no iR-correction. i Demonstration of hydrogen production from PEMWE to drive the hydrogen fuel cell.
