a Schematic of the MEA system. The gaskets are not shown. b Stability test over a span of ~4.5 h of CO2-electrolysis in a 4 cm2-MEA system at the total current density of 120 mA cm−2. c Stability test over a span of ~3.5 h of CO2-electrolysis in a 25 cm2-MEA system at the total current of 12 A. The decrease in ethylene F.E. and the increase in cell voltage may be attributed to the formation of carbonate on the cathode side and the cathode water flooding.
