摘要: A current collector plate, also called a bipolar plate, for a fuel cell includes two facing metal sheets with fluid channels for the fuel (often hydrogen) on the non-facing side of one sheet and fluid channels for air on the non-facing side of the other sheet. Such a plate is made by applying a patterned coating of particles of a soft and reactive metal to at least one of the sheets and rolling them together so that the soft metal particles deform and interact with the facing sheets to selectively join them at the patterned areas. Pressurized fluid is introduced between the sheets to expand non-bonded portions and define the fluid channels.

摘要: In an assembly of facing metal sheets separated by a polymer layer, welded metallurgical bonds are formed between the metal sheets by use of a friction stir weld tool. A rotating tool penetrates the first sheet, locally displaces the encountered portion of polymer film and penetrates into the second sheet. The affected metal of the two sheets is momentarily plasticized and stirred, and the plasticized metal of the two sheets combines to form a weld between the metal sheets. The interposed polymer film may be intended to serve as an adhesive or a vibration damping medium or the like. The facing metal sheets can be layers of facing laminated metal sheet structures that each comprise two metal sheets bonded by an adhesive interlayer.

摘要: One side of a metal sheet is joined to a polymer layer by applying heat to a joining area on the opposite side of the metal. The heat flows through the thin metal to activate a thermoplastic material or heat setting polymer into a bond with the metal. The method can be used to bond the metal sheet to a plastic body or another metal member. It is preferred to use a friction or friction stir tool to heat the metal surface.

摘要: A method for making a current collector plate includes providing a first sheet of material having a first bonding face and a first outer face. A second sheet of material is provided having a second bonding face and a second outer face. A work area is defined on at least one of the first bonding face and the second bonding face. The first and second sheets are bonded together at a bonding area which is different from the work area. The bonded first and second sheet is placed into a die having a pattern defining at least one flow channel. Fluid is injected between the first and second sheets thereby causing at least one of the first and second sheets to project outward at the work area causing at least one flow channel to be formed in the work area as defined by the die pattern.

摘要: Laminated composites such as noise damping sheet metal sandwiches with viscoelastic adhesive cores are strengthened against delamination during forming and made more conductive for welding. Electrically conductive, metal-element containing particles, wires, wire meshes, or the like conductive bonding elements are included in the core material and fused to facing surfaces of the metal sheets to provide many mechanical bonding connections and electrical connections over the bonded area of the composites.
