ABSTRACT:
Current-transmitting components for conducting current between adjacent, planar, stacked high-temperature fuel cells containing solid electrolyte (1) comprising a carrier (7; 10) which determines the geometrical shape and is composed of an oxide-dispersion-hardened nickel or nickel/chromium alloy containing up to 2% by weight of ThO.sub.2 as dispersoid, an electrically conductive Cr.sub.2 O.sub.3 layer (8) and a noble-metal surface layer (9; 12) supported on the latter at the contact/touching faces. Variants having continuous (13; 14) or porous (9; 12) noble-metal surface layer composed of Au, a Pt metal or alloys. Separating plate (4) composed of an oxide-dispersion-hardened nickel/chromium alloy with nickel plating (5) on the fuel side and noble-metal plating (6) on the oxygen side.
