    摘要： The end plates (16) of a fuel cell stack (12) are formed of a thin membrane. Pressure plates (20) exert compressive load through insulation layers (22, 26) to the membrane. Electrical contact between the end plates (16) and electrodes (50, 58) is maintained without deleterious making and breaking of electrical contacts during thermal transients. The thin end plate (16) under compressive load will not distort with a temperature difference across its thickness. Pressure plate (20) experiences a low thermal transient because it is insulated from the cell. The impact on the end plate of any slight deflection created in the pressure plate by temperature difference is minimized by the resilient pressure pad, in the form of insulation, therebetween.

    摘要： An electrolytic cell stack includes inactive electrolyte reservoirs at the upper and lower end portions thereof. The reservoirs are separated from the stack of the complete cells by impermeable, electrically conductive separators. Reservoirs at the negative end are initially low in electrolyte and the reservoirs at the positive end are high in electrolyte fill. During stack operation electrolyte migration from the positive to the negative end will be offset by the inactive reservoir capacity. In combination with the inactive reservoirs, a sealing member of high porosity and low electrolyte retention is employed to limit the electrolyte migration rate.

    摘要： An integrated manifold system for a fuel cell power plant includes a first fuel cell stack and a second fuel cell stack, wherein a common manifold is adapted to be in fluid communication with the first fuel cell stack and the second fuel cell stack. The common manifold includes a first plenum for diverting a first reactant to each of the first and second fuel cell stacks, and a second plenum for accepting the first reactant as the first reactant is exhausted from each of the first and second fuel cell stacks.

    摘要： A fuel cell assembly (110, 210) has a plurality of fuel cell component elements (112) extending between a pair of end plates (114, 115) to form a stack (116), and plural reactant gas manifolds (120, 220; 122, 222; 124, 224; 126, 226) mounted externally of and surrounding the stack, in mutual, close sealing relationship to prevent leakage of reactant gas in the manifolds to the environment external to the manifolds. The reactant gas manifolds are configured and positioned to maximize sealing contact with smooth surfaces of the stack and the manifolds. One embodiment is configured for an oxidant reactant manifold (120, 124) to overlie the region where the fuel reactant manifold (122, 126) engages the stack. Another embodiment further subdivides an oxidant reactant manifold to include a liquid flow channel (270, 274), which liquid flow channel overlies the region where the fuel reactant manifold (122, 126) engages the stack.

    摘要： Fuel is provided to an inlet (14) of a cascade region (15) which has a plurality of stages (17-23), each of which divides fuel flow evenly into a pair of corresponding slots (24-26). The flow is then spread across a floor surface (41) of a cascade exit header (40), the flow spreading into areas between the slots. The flow is then directed into an open cavity which is in fluid communication with the inlets of the fuel flow fields (12) of the fuel cells, reaching the fuel flow field inlets uniformly and simultaneously.
