Abstract
During operation of a high-temperature fuel cell the problem of corrosion of the interconnector on the anode side arises. Accordingly, this problem is substantially prevented by use of at least two metallic functional layers that are applied one above the other on the interconnector. A lower functional layer contains copper and an upper functional layer contains nickel. Functional layers of this type construct a potential threshold for oxygen ions toward the interconnector.
