Hatch well CE, Sammes NM, Tompsett GA, and Brown IWM. Chemical compatibility of chromium-based interconnect related materials with doped cerium oxide electrolyte. J. Eur. Ceram. Soc. 1999 19 1697-1703. 

The interconnect material is vitally important in connecting cells electrically and in separating the reactants. The requirements placed upon it are stringent and range from compatibility with electrodes and chemical stability to corrosion resistance combined with excellent electronic conductivity. The two types of materials that have been extensively used are the chromite ceramics and the chromium-based metallic alloys.
