    Abstract: A battery cell includes a case and an electrode stack disposed within the case. The battery cell includes an anode including a first conductive tab, a cathode including a second conductive tab, and a separator. The battery cell further includes two electrical connections, each attached to one of the first conductive tab or the second conductive tab and to one of a negative terminal and a positive terminal, respectively. The anode, the cathode, and the separator each include a common perimeter including a first portion matching a shape of an interior surface of the case and a second portion including a cut-out configured to recede from the interior surface. The second portion of the anode, the cathode, and the separator are aligned and create a region between the stack and the interior surface. The tabs and electrical connections are disposed within the region.

    Abstract: A bipolar plate for a fuel cell includes a first plate having a first bead seal, and a second plate having a second bead seal. The first bead seal and the second bead seal are disposed opposite each other and extend along a centerline. An outer weld connects the first plate and the second plate together, and extends along an outer weld line. The outer weld line is laterally spaced an outer gap distance from an outer lateral edge of the first and second bead seals. The outer gap distance varies with a position along the centerline to control a stiffness of the bead seals. Positioning the weld line nearer the outer lateral edge increases the stiffness of the raised bead seals in low stiffness areas, whereas positioning the weld line farther from the lateral edge decreases the stiffness of the raised bead seals in high stiffness areas.

    Abstract: A plate structure includes a plate having a planar portion defining a datum plane. The plate includes a raised bead seal and a tunnel protruding away from the datum plane. The raised bead seal extends along a centerline laying on the datum plane. The tunnel extends along a path laying on the datum plane. The tunnel intersects the raised bead seal. The path and the centerline intersect to form a first intersection angle and an adjacent second intersection angle on the datum plane. The first intersection angle and the second intersection angle are supplementary angles. The first intersection angle is an acute angle, and the second intersection angle is an obtuse angle. The path and the centerline are arranged to form a specific value of the first intersection angle and the second intersection angle to control a stiffness of the raised bead seal.

    Abstract: A method of manufacturing a fuel cell stack includes compressing a stack of bipolar plates with a variable applied load a feature non-deformed displacement distance, which is measured from an initial height of the stack of bipolar plates. A first applied load at a first displacement distance and a second applied load at a second displacement distance are sensed. The first displacement distance and the second displacement distance are each less than the feature non-deformed displacement distance. A best fit curve, passing through the first applied load at the first displacement distance and the second applied load at the second displacement distance, is then determined. A final displacement distance, measured from the initial height, is calculated from the best fit curve for a target applied load. The stack of bipolar plates is then compressed to the final displacement distance measured from the initial height.

    Abstract: A plate includes a working face and a header portion. The working face defines a plurality of reactant channels thereon. The header portion is disposed in a peripheral area of the plate and includes a plurality of flanges and a plurality of beads. The flanges are disposed on the header portion and define a plurality of apertures through the plate. Each flange defines a respective one of the apertures. At least one of the apertures is fluidly connected to the reactant channels. The plurality of beads is disposed on the working face. Each bead is disposed about a respective one of the apertures and thereby defines a respective one of the flanges. Each bead defines a shape consisting of bead-corners and bead-sides. Each bead has a sealing surface thereon. The sealing surface is configured to deflect when exposed to a contact pressure to thereby provide a substantially fluid-tight seal.
