ConspectusElectrocatalytic CO2 conversion at near ambient temperatures and pressures offers a potential means of converting waste greenhouse gases into fuels or commodity chemicals (e.g., CO, formic acid, methanol, ethylene, alkanes, alcohols). This process is particularly compelling when driven by excess renewable electricity because the consequent production solar would lead to closing carbon cycle. However, such technology not currently commercially available. While electrolysis in...
Gas-fed CO2 electrochemical flow reactors are appealing platforms for the electrolytic conversion of into fuels and chemical feedstocks at commercially relevant current densities (≥100 mA/cm2). An inherent challenge in development these is delivering sufficient water to cathode sustain reduction reaction, while also preventing accumulation excess porous (i.e., flooding). We present herein experimental evidence showing flooding a zero-gap electrolyzer 200 mA/cm2. This causes 37% decrease...
The distribution and flow of water in a CO<sub>2</sub> electrolyzer can be defined at variable operating conditions using 3D model coupled with an analytical electrolyzer.
