Quantification of water transport in a CO2 electrolyzer

A sufficient supply of water at the catalyst layer is needed to mediate the CO2 reduction reaction (CO2RR), yet too much water favours the competing hydrogen evolution reaction (HER) and lowers the efficiency of CO2 electrolysis. It is therefore important to quantify water at the cathode, but CO2 el...
