  • Patent number: 11631879
    Abstract: The invention relates to a fuel cell module (10) having a plurality of fuel cells forming a fuel cell stack and having an enclosure (14) which surrounds the fuel cell stack. The enclosure (14) includes a bottom assembly and a lid cap assembly (30), wherein the bottom assembly includes a jacket at least partly form-fitted to the stack architecture providing internal alignment functions and a bottom plate in pressure contact with the fuel cell stack, wherein the lid cap assembly (30) comprises a compression plate (32) in pressure contact with the fuel cell stack. The bottom assembly (20) and the lid cap assembly (30) are provided with a progressive locking system providing a range of compression pressures to the fuel cell module (10). Further aspects of the invention relate to a fuel cell system and to a method for producing a fuel cell module (10).

  • Publication number: 20220278347
    Abstract: Flow field plates for fuel cells may include an interior region bounded by an interior boundary that contains openings which, when the flow field plates are stacked, form plural headers extending along a fuel cell stack. A flow field may surround the interior boundary. The headers may include headers for fuel, oxidant and coolant for example. The flow field may include elements that direct flow of a reactant in a radial direction and/or in a circumferential direction. A fuel cell stack may be enclosed in a housing that compresses the stack. In some embodiments plural fuel cells are combined in a power unit in which the fuel cell stacks are received within a fuel cell block equipped with a fluid manifolding stack interface that provides fluid interfaces to the headers of the fuel cell stack.
