Abstract
AbstractThe industrialization of the electrochemical reduction of CO2 toward CO in aqueous electrolytes has recently been started using silver‐based gas diffusion electrodes. The performance of a CO2‐to‐CO electrolyzer model on a 10‐cm2 cell size is assessed with respect to operating pressure, achievable current density at faradaic efficiency of CO above 90 %, composition of gas streams and operational lifetime. Operational lifetime has exceeded 1500 h. The first scaling step to 300 cm2 has been accomplished. The rated power of such a cell is around 300 W.
