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.
In a fuel cell including an electrode, an electrical interconnect comprising:
A fuel cell assembly including a plurality of fuel cells, each of said plurality of fuel cells comprising an electrode and at least one electrical interconnect disposed adjacent said electrode, wherein said interconnect includes a peripheral frame having a central opening, and a central portion disposed in said central opening and attached to said peripheral frame.
