A process is provided for operating a fuel cell system (1), especially in a motor vehicle, wherein the fuel cell system (1) includes at least one reformer (2) and at least one fuel cell (3). To prolong the service life of the system (1), a warm-holding mode is carried out after switching off the fuel cell system (1). During the warm-holding mode an educt containing hydrogen and carbon monoxide is fed to the reformer (2) and reacted with air in reformer (2) at a catalyst (5) of reformer (2) in an exothermal reaction.
