Abstract:
A fuel cell system, comprising:a heat exchanger for preheating a fuel/water mixture; an evaporator unit for generating a starting-material gas flow from the preheated fuel/water mixture; a gas generation unit for producing a hydrogen-rich gas containing carbon monoxide from the starting-material gas flow; a gas cleaning unit for selective removal of carbon monoxide from the hydrogen-rich gas; a cooling unit for the gas cleaning unit; and 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, wherein the heat exchanger is arranged downstream of the gas cleaning unit and through which the cleaned, hydrogen-rich gas flows.
