Abstract
A fuel cell system includes (1) a heat exchanger for preheating a fuel/water mixture; (2) an evaporator unit for generating a starting-material gas flow from the preheated fuel/water mixture; (3) a gas generation unit for producing a hydrogen-rich gas containing carbon monoxide from the starting-material gas flow; (4) a gas cleaning unit for selective removal of carbon monoxide from the hydrogen-rich gas; (5) a cooling unit for the gas cleaning unit; and (6) at least one fuel cell comprising an anode chamber through which cleaned, hydrogen-rich gas flows, a cathode chamber through which an oxygen-containing medium flows, and a cooling space through which a coolant flows. The heat exchanger, through which the cleaned, hydrogen-rich gas flows, is arranged downstream of the gas cleaning unit. Alternatively, the heat exchanger is arranged downstream of the cooling space and through which the coolant flows.
