Abstract:
A fuel cell stack compression system in which a spring assembly and mechanical linkage assembly are used in conjunction with tie rods and tie bars to apply a compressive load to a fuel cell stack. The linkage assembly includes a lever and three pins to redirect the force or movement generated by the spring assembly into a movement or force for the tie rods. The tie rods, in turn, connect to the tie bars which span the top end plate of the fuel cell stack and transfer the load to the stack. The linkage also includes a slotted bearing which compensates for the circular arc formed by the lever and allows the spring assembly to be rigidly mounted under the bottom end plate. The spring assembly comprises multiple springs arranged in parallel and designed to provide a non-linearly decreasing load as the stack compresses due to cell consolidation. This load profile reduces overall stack shrinkage while providing high pressure at the beginning of life to insure proper cell-to-cell contact.

Abstract:
A fuel cell stack manifold system in which a flexible manifold body includes a pan having a central area, sidewall extending outward from the periphery of the central area, and at least one compound fold comprising a central area fold connecting adjacent portions of the central area and extending between opposite sides of the central area, and a sidewall fold connecting adjacent portions of the sidewall. The manifold system further includes a rail assembly for attachment to the manifold body and adapted to receive pins by which dielectric insulators are joined to the manifold assembly.

Abstract:
A fuel cell gasket assembly for use in conjunction with a fuel cell stack by placing the gasket assembly between the periphery of a face of the stack and a manifold. The periphery of the stack face includes periphery portions that expand differently during operation of the stack. The gasket assembly comprises a member adapted to have different compressibilities over predetermined portions of the member and/or a resilient shim embedded in preselected sections the member whereby the gasket maintains contact with the periphery of the stack face and the manifold. The structure of the gasket assembly of the present invention provides a compliant fuel cell gasket assembly that accommodates bipolar plate growth and end cell growth in the fuel cell stack and maintains the gas seal between the stack and manifold structure.

Abstract:
A modular fuel cell stack assembly comprising a plurality of fuel cell stacks, each of the stacks having a plurality of stack faces and a plurality of stack corners formed between the stack faces, wherein the plurality of stack faces include a cathode inlet face adapted to receive oxidant gas for use in a cathode side of the fuel cell stack, a cathode outlet face adapted to output cathode exhaust from the cathode side, an anode inlet face adapted to receive fuel for use in an anode side of the fuel cell stack and an anode outlet face adapted to output anode exhaust from the anode side, and wherein at least one of the cathode inlet face, cathode outlet face, anode inlet face and anode outlet face is an open face without a manifold, and a containment structure for housing the plurality of fuel cell stacks and for providing fuel and oxidant gas to said fuel cell stacks, the containment structure including at least one sealed chamber for sealingly enclosing and isolating at least one open face. Also provided is a modular fuel cell assembly comprising a plurality of fuel cell stacks, an oxidizer disposed centrally of the fuel cell stacks and adapted to receive anode exhaust from the fuel cell stacks, to generate oxidant gas using the anode exhaust and to distribute the oxidant gas to the fuel cell stacks, and a containment structure for housing the plurality of fuel cell stacks and the oxidizer and adapted to receive fuel and distribute the fuel to the fuel cell stacks.
