Abstract
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.
