The invention relates to a catalyst for the oxidation of carbon monoxide (CO) at low temperatures, which is a catalytically active composition based on platinum and cobalt. The catalyst can be used in the removal of CO from hydrogen-rich gas for fuel cell technology in order to avoid poisoning the electrodes with CO. Further fields of application relate to the automobile sector, and in particular, to the effective removal of CO during cold starting of a diesel or petrol engine and also to air purification systems for quality control of air in interior spaces, e.g., the removal of CO in a tunnel, an underground railway, multi-story car parks or submarines. |
