摘要： A hydrogen fuel cell stack (10) has at least two segments (12, 14) of fuel cells each having reactant gas passages (26, 36). The reactant gas passages (26, 36) of each fuel cell in each segment (12, 14) are arranged in parallel with each other. Flow of fuel cell fluids is in a gravity assisted downward direction. Gravity assisted flow directs water formed in each cell to lower removal points of the stack segments (12, 14). Adjacent segments (12, 14) are separated by either a separator segment (16) formed as an integral unit with the stack or the segments (12, 14) are joined and an external piping system directs flow to differing stack areas. A cathode flow enters at a first stack end and a hydrogen anode flow enters the stack at an opposite end, such that cathode and anode flows are counter-current to each other. A coolant flow is normally injected adjacent to and flows parallel with the cathode flow, but can also be directed by the piping system to any or all segments (12, 14) in series or parallel.

摘要： The present invention discloses a stamped bridge member that defines a flow path between a header and a flow field on a fuel cell plate. The bridge member provides a support surface on which a seal can be positioned to seal the plate against adjacent plates or MEAs. The fuel cell plates can be stamped plates with two surfaces each having flow fields thereon. The flow fields maintain a fluid flowing between a supply header and a return header on a single surface of the plate. The ends of the flow fields can taper relative to the supply and return apertures to provide for a desired flow distribution through the flow field.

摘要： A seal configuration is provided for a fuel cell stack, including a first bipolar plate and a second bipolar plate, each disposed on opposite sides of a membrane electrode assembly. The seal configuration includes a first sub-gasket adhered to a recess region of the first bipolar plate and a second sub-gasket adhered to a recess region of the second bipolar plate wherein the first and second sub-gaskets are disposed on opposite sides of the membrane electrode assembly. A seal member is disposed in the recessed regions of the first and second bipolar plates and between the first and second sub-gaskets. The seal configuration minimizes the size of the bypass regions around the seal perimeter and provide better control of the positions of all components during assembly of the fuel cell stack. The approach also reduces sensitivity to ambient relative humidity variations and reduces manufacturing costs by eliminating the need for humidity control in the production area.

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.

摘要： The present invention isolates the fluid streams flowing into and out of a fuel cell stack from the terminal plates so that the fluid streams and terminal plates do not come into contact with one another. The prevention of the fluid streams from contacting the terminal plate eliminates corrosion concerns associated with the terminal plate. The present invention accomplishes this isolation through the use of headers having fluid passageways therein that route the fluid streams in and/or out of the fuel cell stack while preventing contact between the fluid streams and the terminal plate.
