摘要： Apparatus for mixing fuel and an oxidant for use in an autothermal reformer that provides hydrogen to a fuel cell. The apparatus includes a mixing vessel (10), a first inlet (4) to the mixing vessel for movement of gaseous fuel or oxidant therethrough, a second inlet for movement of gaseous fuel or oxidant therethrough, and an exit (60) from the vessel adjacent the autothermal reformer. The discharge ends of the inlets are spaced apart from each other and from the exit which is near a POX reactor (61) that combusts the mixture of fuel and oxidant exiting from the mixing vessel. The first inlet is comprised of a plate (26) with a plurality of tubes (24) extending therefrom through which fuel or oxidant passes. The tubes extend into the mixing vessel and towards the exit of the vessel such that the fuel does not come into contact with the oxidant until the gaseous fuel or oxidant discharges from the ends (30) of the tubes thereby mixing the fuel with the oxidant in the gaseous state prior to passing to the POX reactor.

摘要： A fuel cell stack that includes straight cathode flow channels and straight anode flow channels through a seal area between bipolar plates in the stack. The fuel cell stack includes a seal that extends around the active area of the stack and between the stack headers and the active area. At the locations where the cathode flow channels extend through a seal area to the cathode input header and the cathode outlet header, and the anode flow channels extend through a seal area to the anode input header and the anode output header, the diffusion media layer on one side of the membrane is extended to provide the seal load. Alternately, shims can be used to carry the seal load.

摘要： A fuel cell in a fuel cell stack that provides a transition from nested bipolar plates in the active region of the stack to non-nested bipolar plates in the inactive regions of the stack without giving up the reduced stack thickness provided by the nested plates or changing the size of the flow channels. Particularly, the diffusion media layers in the fuel cells are removed in the inactive regions where the bipolar plates are non-nested so that the volume necessary to maintain the size of the flow channels is provided without the need to increase the distance between adjacent MEAs. A thin shim can be provided between the membranes and the plates in the inactive regions to support the membrane where the diffusion media layer has been removed to prevent the membrane from intruding into the flow channels and blocking the reactive flow.
