Abstract
An electrical interconnect device for a planar fuel cell having solid oxide electrolyte, a cathode and a nickel-containing anode comprises a plate-like chromium-containing substrate having fuel gas-flow channels on one side and an oxidation-resistant coating on surfaces of the one side adapted to contact the anode. The coating comprises an outer oxygen barrier layer for electrically contacting the anode comprising Ni, a noble metal except Ag or an alloy of one or more of these metals and an electrically conductive metal barrier layer comprising Nb, Ta, Ag or alloys of one or more of these metals between the substrate and the outer layer.
