    摘要： A manufacturing arrangement for a fuel cell stack or at least a unit fuel cell of the fuel cell stack includes at least a pre-arrangement site for arranging a membrane electrode assembly and a bipolar plate in a predefined orientation to each other, wherein the bipolar plate has at least one opening and/or at least one specific contour, and wherein the membrane electrode assembly and the bipolar plate are oriented to each other in such a way that the membrane electrode assembly covers at least one opening in the bipolar plate and/or extends over the bipolar plate in at least one area; wherein the manufacturing arrangement further includes at least one cutting site with a cutting device which is adapted to cut the membrane electrode assembly in a predetermined area so that the membrane electrode assembly has a cut opening, which resembles the at least one opening of the bipolar plate, and/or at least one cut contour, which resembles the at least one contour of the bipolar plate, and/or at least one cut alignment structure for aligning the unit fuel cells in a fuel cell stack, as well as a corresponding manufacturing method.

    摘要： In order to prevent a reduction in workability when inserting an insulator, the insulator is to be disposed between a stacked body having a cell stack including a plurality of stacked unit cells and an end member to be disposed outward from the cell stack in stacking directions of the plurality of unit cells, and a covering to be disposed so as to separate in a perpendicular direction to the stacking directions from a side face of the stacked body parallel to the stacking directions. In a state where an end portion of the end member in the perpendicular direction is closer to the covering than an end portion of the cell stack in the perpendicular direction, and the insulator is disposed between the stacked body and the covering, the insulator includes a planar portion for covering at least a part of the side face, and a protruded portion disposed in the planar portion and protruded toward one or more unit cells near the end member among the plurality of unit cells constituting the cell stack.

    摘要： An electrical connection system for cell voltage monitoring in a fuel cell stack. A fuel cell stack assembly comprises a plurality of fuel cells disposed in a stacked configuration, each cell substantially parallel to an x-y plane and including an electrical tab extending laterally from an edge of a plate in the cell in the x-direction to form an array of tabs extending along a side face of the fuel cell stack in a z-direction orthogonal to the x-y plane. A connector device comprises a planar member having a plurality of spaced-apart slits formed in an edge of the planar member, each slit having an electrically conductive material on an inside face of the slit. The slits are spaced along the edge of the planar member and configured to receive the tabs by sliding engagement in the y-direction. Alternatively, each tab may be crimped to create a distortion in the tab out of the x-y plane of the plate and a connector device comprises a planar member having a plurality of generally parallel slits formed in the body of the planar member, each slit having an electrically conductive material on an inside face of the slit, the slits being spaced within the planar member and configured to receive the tabs by sliding engagement in the x-direction so that each tab engages with at least a portion of the electrically conductive material on the inside face of a respective slit.

    摘要： A fuel cell pack is disclosed. The fuel cell pack has N membrane electrode assemblies, N−1 connected conductive planes, an independent first electrode conductive layer, and an independent second electrode conductive layer, wherein N is an integer and 2≦N≦3000. Each connected conductive plane has a first electrode conductive layer and a second electrode conductive layer, wherein the first electrode conductive layer connects to the second electrode conductive layer. The independent first electrode conductive layer is corresponding to the second electrode conductive layer of the N−1th connected conductive plane; the independent second electrode conductive layer is corresponding to the first electrode conductive layer of the 1st connected conductive plane. Each membrane electrode assembly is situated between each first electrode conductive layer and the second electrode conductive layer to form a fuel cell.

    摘要： A method for operating a passive, air-breathing fuel cell system is described. In one embodiment, the system comprises one or more fuel cells, and a closed fuel plenum connected to a fuel supply. In some embodiments of the method, the fuel cell cathodes are exposed to ambient air, and the fuel is supplied to the anodes via the fuel plenum at a pressure greater than that of the ambient air.
