Abstract: A fuel cell gas separator (212) for use between two solid oxide fuel cells (210) and having a separator body with an anode-facing side and a cathode-facing side and with paths (234) of electrically conductive material therethrough in an electrode-contacting zone (236). In a first aspect, the electrically conductive material comprises a silver-glass composite, preferably containing 15 to 30 wt % glass. In this aspect the material of the separator body is preferably zirconia and the silver is commercially pure, a silver mixture or a silver alloy. In another aspect, the material of the separator body is zirconia, the electrically conductive material comprises silver or a silver-based material, a coating of nickel is formed on the electrode-contacting zone (236) on the anode-facing side preferably with an undercoating of Ag, and a coating of Ag—Sn alloy is formed on the electrode-contacting zone (236) on the cathode side.
