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...
Bicarbonate electrolysers convert carbon capture solutions into chemicals and fuels bypass the need for energy-intensive CO 2 recovery. Porous metal electrodes are more effective than composite this type of electrolyser.
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.
Electroplated 3D printed flow field plates are demonstrated for the electrolysis of water to hydrogen fuels.
We present an analytical electrolyzer with sensors embedded within flow plates to enable direct measurement of electrolyte temperatures and pressures in real time during water electrolysis. Flow either parallel or serpentine channels a total eight equally spaced were integrated into cell containing nickel foam gas diffusion layer anion exchange membrane.
