Abstract
Methods and/or systems for operating a carbon oxide reduction electrolyzer may involve (a) performing normal operation at the electrolyzer; (b) performing a recovery or protection process including: (i) applying a modified current and/or voltage to the electrolyzer, and (ii) while applying the reverse current to the electrolyzer, flowing a recovery gas to the cathode; and (c) resuming normal operation at the electrolyzer. Applying a modified current and/or voltage may involve applying a short circuit to the electrolyzer, holding the electrolyzer electrodes at open circuit voltage, and/or applying a reverse current to the electrolyzer.
