Abstract
A method for removing carbon monoxide from a gas stream, in which the gas stream loaded with CO is guided through a device, and the CO is removed from the gas stream through adsorption on the working electrode. As a function of an electrical voltage between the working electrode and the counter electrode, or between the working electrode and the reference electrode, an electrode cleaning mode is enabled by triggering a current flow between the working electrode and the counter electrode, and the CO adsorbed on the working electrode is oxidized to CO .01.
