CO<sub>2</sub> flow electrolysis – limiting impact of heat and gas evolution in the electrolyte gap on current density
Christina Martens, Bernhard Schmid, Hermann Tempel, Rüdiger‐A. Eichel
Abstract
This study investigates the effects of high current density CO 2 electrolysis on the operation of GDE flow cells. It reports a new method of identifying windows of steady-state operation, complementing GDE optimization from a system-perspective.
