A gas generating system for a fuel cell system as well as to a method of operating same. In order to provide hydrogen-containing combustible gas as rapidly as possible and to reduce the exhaust gas emissions, for the start of the operation of the gas generating system, at least one catalytic burner is started and the generated heat is used for evaporating a combustion agent and/or water and for the heating-up of an additionally connected partial reforming unit or partial oxidation stage in order to generate a hydrogen-containing gas for the fuel cell unit by reforming or partial oxidation.

Gas generating system for a fuel cell system and method of operating a gas generating system

A system for generating hydrogen-rich gas has a reformer for catalytic water vapor reforming of a water vapor/fuel mixture by an input supply of thermal energy, and a CO oxidation stage for removing carbon monoxide from the hydrogen-rich gas while emitting heat, with the reformer and the CO oxidation stage being thermally coupled. An oxygen quantity fed to the CO oxidation stage is adjusted as a function of the gas temperature in or at the output of the reformer/oxidation stage. This can take place by an automatic (feedback) control, a combination of open loop control and automatic control or by an adaptive characteristic diagram.
