    摘要: In a device for providing heating energy to a gas-generating system by means of essentially complete catalytic combustion of a fuel on a suitable catalyst material, heat energy is transferred directly or by means of a heat-conducting medium from the catalytic burner to the gas-generating system. To improve the starting behavior and the exhaust emissions, the device comprises three components that are at least temporarily traversed by fuel, with a cold-start component having an electrical heating device. The central component is preferably designed as a filter press with an integrated heat exchanger. A third, unheated, stage is also provided for residual gas combustion.

    摘要: A system for supplying an evaporated and/or superheated hydrocarbon or hydrocarbon/water mixture to at least two components of a gas generation system of a fuel cell system, in particular to at least two stages of a multi-stage reforming process. In one embodiment, the system contains at least two heat exchangers, each of which contains a media-side area and an area that serves to input thermal energy. Furthermore, each of the heat exchangers is connected to least one of the components of the gas generation system and the two heat exchangers are connected to each other. In an alternate embodiment, the system contains one heat exchanger, the media-side area of which is connected to a valve device, which distributes the evaporated and/or superheated mixture to at least two conduits, each of which leads to one of the two components of the gas generation system.
