International Classification:

B23K001/00

US Classification:

228/101000

Abstract:

Methods of and devices for continuously casting molten material onto one or more surfaces of a moving substrate to provide one or more profiles on one or more surfaces are disclosed in the present invention. In a preferred embodiment, the casting method includes providing a substrate, heated reservoir of a molten material, and a casting die; moving the substrate past the casting die into which the molten material is introduced; containing the molten material against the one or more surfaces of the moving substrate; heating the casting die to prevent the molten material from solidifying prematurely; and cooling the molten material to solidify the molten material to provide one or more profiles on the one or more surfaces of the moving substrate and to bond the solidified profile(s) to the one or more surfaces. In a preferred embodiment, the device for casting and bonding a molten material to one or more surfaces of a moving substrate includes a casting die for wetting the moving substrate with the molten material to provide one or more desired profiles on one or more surfaces of the moving substrate; a heating system to prevent molten material from solidifying in the casting die; and a cooling device for solidify the molten material in the desired profile(s) and for bonding the desired profile(s) to the one or more surfaces of the moving substrate.

International Classification:

H01M008/02

US Classification:

429/034000, 429/035000, 429/038000, 428/618000

Abstract:

A niobium-clad bipolar plate for use in a proton exchange membrane fuel cell is disclosed, whereby the electrically conductive, corrosion resistant niobium cladding protects a highly electrically conductive base metal in a harsh environment for the purpose of communicating electrical energy from the cathode of one membrane-electrode assembly to the anode of a second membrane-electrode assembly. Alternatively, the niobium-clad bipolar plate can include a titanium interlayer, interposed between the niobium cladding and the base metal. Also disclosed is a system for producing electricity using a niobium-clad bipolar plate in combination with numerous membrane-electrode assemblies to provide electrical energy and a proton exchange membrane fuel cell comprising a niobium clad-bipolar plate.

Appl. No.:

6/221591

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

B23K 1116
B23K 1134

US Classification:

219118

Abstract:

After measuring the bulk resistance the surface of high strength low alloy steel material is treated to form a high resistance coating on its surface. When resistance welding the material the coating permits weld formation without significant expulsion or excessive electrode force over a wide range of operating conditions.

Abstract:

A tempering process for tempering an aluminum alloy coil includes a first reel-to-reel process including an anneal to solutionize the aluminum alloy followed by a quench, a second reel-to-reel process comprising rolling reduction, and a hardening anneal performed on the aluminum alloy coil. Cladding may be performed during the second reel-to-reel process; or a subsequent reel-to-reel electroplating process may be performed including an alkaline soak clean, an alkaline microetch and seed electroplating, and aqueous electroplating of a contact metal onto the seed electroplating. Electrical interconnect components may be stamped from the tempered and clad or electroplated aluminum alloy coil. The electrical interconnect components may, for example, be connectors, lead frames, or bus bars.
