Abstract:
A device for evaporating and/or superheating a hydrocarbon or a hydrocarbon/water mixture for a gas generation system of a fuel cell, comprising:a first heat exchanger having a media-side region through which the hydrocarbon or the hydrocarbon/water mixture flows, wherein the media-side region is in thermally-conductive communication with a heat-transfer-side region of the first heat exchanger; a burner arranged upstream of the heat-transfer-side region of the heat exchanger, wherein an exhaust gas from the burner flows through the heat-transfer-side region of the first heat exchanger; and at least one second heat exchanger having a media-side region through which the hydrocarbon or the hydrocarbon/water mixture flows, wherein the media-side region is in thermally-conductive communication with a heat-transfer-side region of the second heat exchanger, wherein the exhaust gas stream from the heat-transfer-side region of the first heat exchanger flows through the heat-transfer-side region of the second heat exchanger, wherein the at least one second heat exchanger has a greater mass than the first heat exchanger.
