From: Undoped ruthenium oxide as a stable catalyst for the acidic oxygen evolution reaction
a The PEMWE performance curves with the anh-RuO2 anode, h-RuOx anode and the commercial IrO2 anode. The electrolyzer performance curves are presented as non-iR corrected. b A comparison of voltages for operating the PEMWEs at different current densities. c Nyquist plots from the galvanostatic EIS measurements at 100 mA cm‒2. PEMWE stability test with (d), the anh-RuO2 anode, and (e), the h-RuOx anode for operating at 1 A cm‒2. f Chronoamperometric tests conducted under RDE system at 10 mA cm‒2. g Pictures showing the color of the anode circulating water before and after filtration as collected from the failed PEMWE with the h-RuOx anode. Source data are provided as a Source Data file.
