Abstract
A method for shortening the cold starting time of a CO oxidation catalytic converter in a vehicle with an integrated fuel cell system. According to the invention, gas components which delay the start are removed from the reformate gas of the gas-generating system using an adsorber during the cooling-down phase after the vehicle has been switched off.
