A component for an electrochemical cell is formed by additive manufacturing process. The additive manufacturing process can be repeated to produce fuel cell stack.

Method of making components for an electrochemical cell and an electrochemical cell and cell stack

A composite shaft assembly including a core structure formed by weaving fiber(s) into an open composite structure. The assembly further includes a first end piece and a second end piece having helically shaped groove(s) and/or axially groove(s) on an outer surface of an end portion of the first and second end piece. Woven into the helical and/or axial groove(s) on the first end piece and at least partially within through hole(s) disposed at an end of the groove(s) is the fiber(s) at a first end portion of the of the core structure. Woven into the helical and/or axial groove(s) on the second end piece and at least partially within through hole(s) disposed at an end of the groove(s) is the fiber(s) at a second end portion of the of the core structure. Structural adhesive(s) are applied over the fiber(s) and allowed to cure to form the composite drive shaft.

Open composite shaft

A method of welding two workpieces together is described. A conductor in electrical communication with a pulse circuit is provided. A portion of the second workpiece is located adjacent the conductor. The two workpieces are also located together. A portion, or all, of one workpiece is welded to the other by applying a pulse current to one of the workpieces. A method of forming a workpiece is disclosed using a pulse current to move the workpiece into a desired shape.
