    摘要: A method is provided for brazing a metal leadframe clip to an electrical resistance heating tip for an electrical resistance igniter, wherein the electrical resistance heating tip includes silicon carbide. The method includes forming a layer of SiO2/Al2O3 on a surface of the electrical resistance heating tip; applying a braze alloy paste between the layer of SiO2/Al2O3 and the metal leadframe clip; and heating the braze alloy, the metal leadframe clip and the electrical resistance heating tip to fuse the braze alloy.

    摘要: An electrical interconnect for a fuel cell assembly comprising a peripheral frame formed of one or more materials having a coefficient of thermal expansion similar to that of adjacent elements to which the interconnect must be bonded and a central portion formed of a corrosion-resistant material for conducting electric current between adjacent fuel cells. Preferably, the central portion is attached to the peripheral frame via a brazed corrugated lap joint for relieving thermal expansion differences between the frame and the central portion. Preferably, the joint includes an interlayer of a ductile material, for example, a nickel, copper, silver or gold layer, which helps to relieve thermal stress between the frame and the central portion.
