Abstract

A device is used to evaporate and/or superheat a hydrocarbon or a hydrocarbon/water mixture for a gas generation system of a fuel cell installation. The hydrocarbon or the hydrocarbon/water mixture flows through a medium-side region of a heat exchanger, which is in thermally conductive communication with a heat-transfer-side region of the heat exchanger. A burner is arranged upstream of the heat-transfer-side region of the heat exchanger, as seen in the direction of flow. An exhaust gas from a combustion which takes place in the burner flows through the heat-transfer-side region of the heat exchanger.
