a cell voltage, iR-free cell voltage and high-frequency resistance (HFR) over current density. b Faraday efficiencies of CO and H2 of cell 2. c partial current densities of CO and H2 (cell 2). The cell comprised a Sustainion® membrane, an IrO2 anode and an Ag cathode (all purchased from Dioxide Materials™). Measured at ambient temperature (23 ± 3 °C), with a bubbler at 50 °C humidifying the cathode gas stream (47.5 sccm CO2 and 2.5 sccm N2) and 0.1 KOH anolyte circulated at 20 mL min−1.
