Abstract
In a method and apparatus for producing a hydrogenous gas stream for a fuel cell system, the share of CO contained in the gas stream, is reduced by providing one or more selective oxidation stages which preferably are thermally coupled to a reformer for the reforming of hydrocarbons, or to a heat exchanger. In order to supply the fuel cell system, as quickly as possible, with a hydrogenous gas stream having a low share of CO, so that it can be placed in operation at the temperature of the surrounding environment, one or more additional, thermally decoupled, selective oxidation stages is series-connected to the existing selective oxidation stages at the beginning or end of the series, or at intermediate points.
