A fuel cell module () with a fuel cell (), a residual gas burner () and a heat exchanger (). The service life of the module () can be improved by at least one compensator () for establishing a flow-carrying connection between the residual gas burner () and the heat exchanger ().

Fuel cell module

The invention relates to a plate-type heat exchanger having a plate block comprising partition plates which delimit flow channel layers between the plates. According to the invention, the partition plates have a solid or folded edge, which projects out of the plane of at least one main side of the partition plates at the edge side, along closed-edge regions which are spaced apart from one another in the peripheral direction by means of intervening open-edge regions. In the plate block, this solid or folded edge is joined in a fluid-tight manner to the opposite edge region of an adjoining partition plate and functions as a lateral boundary for the associated flow channel layer. Such heat exchangers may be used, for example, in automobiles and reactors of fuel cell systems.

Plate-type heat exchanger

The invention relates to a heat exchanger of the crosscurrent type, through which at least two fluids flow, consisting of plates which are stacked one on the other between two cover plates and which are spaced from one another in regions and are in contact in regions, so that fluid paths are formed between them in a heat transfer region, and of inlet ducts and outlet ducts which are arranged laterally in duct regions and which are formed from inlet duct openings and outlet duct openings in the plates, at least one inlet duct and one outlet duct being fluidically connected to a group of fluid paths which are next but one. The object of the invention is to develop a heat exchanger of the type initially mentioned, in such a way that, while having at least the same operating reliability, it can be produced more efficiently and more cost-effectively and has a lower weight. In order to achieve this object, there is provision for the spacing of the plates to be carried out by means of shaped-out portions of the plates.

Heat exchanger of the crosscurrent type

Heat transfer device of a stacked plate construction has a stacked plate construction consisting of alternately stacked flow duct plate units with flow duct openings and connection duct openings as well as connection cover plate units with connection duct openings provided such that two separate fluid flow systems are formed. The equal-sided connection duct openings overlap only by means of an interior portion with the equal-sided ends of the flow duct openings, whereas, by means of an exterior portion, while forming a respective connection conduit, they extend in the area outside the flow duct openings. This implements a compact plate stack construction with an optimal connection geometry for very low pressure losses.
