摘要： An electro-chemical fuel cell stack (20) having a fuel cell assembly (24) disposed between upper and lower terminal plates (56) which are disposed between upper and lower end plates (45, 58). Optionally, spacer plates (52) can be inserted between the end plates (45, 58) and the terminal plates (56). The end plates (45, 58) and/or the spacer plates (52) may have contoured surfaces to apply a generally uniform compressive load on the fuel cell assembly (24). The terminal plates (56), spacer plates (52), and end plates (45, 58) may be connected together to form rigid end assemblies (32, 34) that compress the fuel cell assembly (24).

摘要： A PEM fuel cell (10) includes a cathode plate (22) for directing a first fluid along a surface thereof. An anode plate (20) directs a second fluid along a surface thereof. An MEA (12) is oriented in a first direction. The MEA (12) includes an anode face opposing the anode plate (20) and a cathode face opposing the cathode plate (22). A plate margin includes first and second header apertures oriented in a second direction perpendicular to the first direction. A first seal (16a) is disposed between the anode plate (20) and the MEA (12). The first seal (16a) defines a first fluid communication path between the first header aperture and the anode plate (20). A second seal (16c) is disposed between the cathode plate (22) and the MEA (12). The second seal (16c) defines a second fluid communication path between the second header aperture and the cathode plate (22). The first and second seals allow the first and second fluid to flow through respective passages thereon in a direction parallel the first direction.

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 sensor (116) for monitoring the lambda of a component of a reactant feed stream (86) flowing through a fuel cell stack (32). The sensor (116) comprises one or more fuel cells (94) that are sensitive to a change in lambda of a specific component of a reactant feed stream (86) flowing through the fuel cell (94). The sensitivity of the fuel cell (94) causes a voltage produced by the lambda of the specific component. The variation of the voltage output can be modeled and/or compared to empirical data to correlate the voltage output to the lambda of the specific component. Based on the lambda of the specific component, the operation of the fuel cell stack (32) can be optimized.

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.
