Abstract
A solid oxide fuel cell interconnector having a superalloy metallic layer with an anode facing face and a cathode facing face and a metal layer on the anode facing face of the superalloy metallic layer, the metal layer including a metal which reacts with Cr.sub.2 O.sub.3 to form an electronically conducting oxide phase on the superalloy metallic layer. In accordance with one particularly preferred embodiment, a second metal layer is disposed between the metal layer and the superalloy metallic layer, the second metal layer including a metal which does not oxidize in a fuel atmosphere.
