Abstract

See full text

A gas-generating device includes at least one reforming reactor, one CO shift reactor with associated cooling device and one gas cleaning unit for selective catalytic oxidation of the carbon monoxide in the hydrogen-containing gas with associated cooling device. A fuel cell is connected downstream of the gas-generating device. The cooling device associated with the CO shift reactor comprises a line for the cathode discharge air current and the cooling device associated with the gas cleaning unit comprises a line for the anode gas discharge current. During a method for starting the gas-generating device, only fuel and air are fed into the reforming reactor at the start and the fuel cell is bypassed using a bypass line. After the starting phase, water is additionally fed into the reforming reactor and the bypass line is closed.
