To generate hydrogen-rich gas which is supplied to a fuel cell stack (2) of a fuel cell power plant, a reformer (1) generates reformate gas comprising hydrogen from methanol, and a carbon monoxide oxidizer (3) oxidizes carbon monoxide from the reformate ga...

Fuel cell system comprises a gas production device for catalysis of a water vapor/fuel mixture and/or for the partial oxidation of an oxygen/fuel mixture to produce a hydrogen-rich medium, and a gas purification stage for removing carbon monoxide from the ...
