inletting a gas comprising COx to the cathode of the MEA and applying a current to the MEA at a first current density, to thereby reduce COx and produce a COx reduction product; and
during operation to produce the COx reduction product for a downstream process, automatically pausing applied current according to a current pause schedule.
