    摘要: A fuel cell includes a fuel cell stack. A pressure plate is arranged on one side of the fuel cell stack. The pressure plate includes a hole, and a tie rod assembly has a tie rod received in the hole. A nut with a conical surface is secured to the tie rod. An isolator is arranged in the hole between the tie rod assembly and the pressure plate. The isolator has a conical portion, and the conical surface engages the conical portion to provide a conical interface. The tie rod assembly applies a clamp load on the fuel cell stack via the conical interface.

    摘要: A bipolar plate for an electrochemical system. The bipolar plate comprising a first individual plate and a second individual plate which are joined together. Each individual plate comprising: an electrochemically active region, an outer edge, and a perimeter sealing element. The outer edge region spans between the edge of the perimeter sealing element and the outer edge. Some emobidments of the outer edges protrude out of a plate plane defined by the bipolar plate. A plurality of stiffening structures stiffening the outer edge region of the bipolar plate.

    摘要: A fuel cell stack includes a stack body formed by stacking a plurality of fuel cells together in a stacking direction. A second end plate is provided at one end of the stack body in the stacking direction. A pair of coolant supply passages are provided at upper and lower positions of the second end plate for allowing a coolant to flow into the fuel cells. A coolant supply manifold member is attached to the second end plate, and an insulating plate is provided between the second end plate and the coolant supply manifold member.

    摘要: The invention relates to a separator plate for an electrochemical system, comprising a first and a second plate, which are essentially congruently arranged on top of one another. The first and/or second plates furthermore include at least one elongated projection, which protrudes on opposite sides from a plate plane of the separator plate and extends along the plate plane from an outer edge to an interior of the separator plate so that the projection of the first plate and/or the projection of the second plate, if necessary together, form a receptacle for a connector pin. The projection of the first plate or the projection of the second plate includes an indentation directed toward the respective opposite plate for fixing the connector pin in the receptacle in a force-fit and/or form-locked manner.

    摘要: The present invention provides a fuel cell cap that includes a flanged edge region in which a gasket is positioned, and which is adapted to be sealingly fit over the edge of fuel cell and successive heat energy transmitting sections that concentrate the heat energy for ultimate emission. A dome-shaped first region is integral with and positioned radially inward from the flanged edge region followed by a first stack region of cylindrical cross-sectional shape that is integral with and extending upwardly from the dome-shaped first region. Next, a second stack region of cylindrical cross-section shape extends upwardly from the first stack region and is of a second diameter smaller than the first diameter. Finally, an inwardly tapering region extends upwardly from the second stack region and emits the heat energy from the cap.

    摘要: A separator plate for an electrochemical system has two metal individual plates. The plates have passage openings for operating media and possibly coolant, and distribution structures. The distribution structures are formed in the metal individual plates and which each communicate with at least two of the passage openings. A peripherally extending sealing structure is formed in each of the metal individual plates at least peripherally around the electrochemically active region and at a distance therefrom and/or peripherally around at least one of the passage openings and at a distance from the edge thereof. The cross-section of the sealing structure has a bead roof, two bead flanks, and at least in some segments, two bead feet. At least in the region of the bead roof of the sealing structure at least in some segments, the sealing structure extends sinuously with at least two wave periods having convex and concave segments.

    摘要: A fuel cell stack is described. The fuel cell stack comprises an interconnect assembly comprising a cathode-side interface coupled to an interconnect via a first joint, and an anode-side interface coupled to the interconnect via a second joint, the interconnect assembly having a first coefficient of thermal expansion (CTE) at an interface side of the interconnect assembly. The fuel cell stack further comprises a fuel cell element coupled to the interconnect assembly at the interface side via a hermetic seal, the fuel cell element having a second CTE at the interface side, the first CTE and the second CTE satisfying a predetermined CTE matching condition.
