A fuel cell comprises an anode, a cathode, a solid electrolyte disposed between the anode and the cathode, and interconnect means for providing an electrical connection located adjacent to either the cathode or the anode but not adjacent to the solid electrolyte. The interconnect means includes an interconnect layer having a composition of (i) a mixture of an electrical conductor and a ceramic matrix material that is sinterable in an oxidizing atmosphere at a temperature of less than about 1500 DEG C., (ii) a mixture of a lanthanum chromite-based ceramic and a yttrium chromite-based ceramic, or (iii) a yttrium chromite-based ceramic of the form Yw-x-yCaxZryCrv-zZnzO3 , where w is from about 0.9 to about 1.1, x is from about 0.1 to about 0.3, y is from about 0.001 to about 0.1, z is from about 0.1 to about 0.3, and v is from about 1 to about 1.2.
