The high-pressure metal wire counter (auxiliary) electrode is provided in the high-pressure electrochemical cell as a current sink to shunt excess current away from the reference electrode. The counter electrode is generally chosen to be inert under reaction conditions, typically platinum, rhodium, palladium, or gold wire. It fits aqueous and organic solvent electrolyte requirements well.

Application note The high-pressure metal wire electrode is installed in the high-pressure cell lid to be immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. The high-pressure electrodes should be installed in the high-pressure cell using Swagelok electrode fitting 6 mm OD. After the process, the electrode should be washed several times with isopropanol or ethanol and dried under the nitrogen flow.
