AbstractNovel TiN-Ni cermets with high oxidation resistance and excellent electrical conductivity were developed and evaluated as intermediate-temperature solid oxide fuel cells (IT-SOFCs) interconnects. Three TiN-Ni cermets with 30 vol.%, 50 vol.% and 70 vol.% Ni were prepared by optimizing hot-pressed sintering parameters. Their oxidation kinetics was systematically investigated in air at 600-800 degrees C. Relative density, oxidation rate constant and electrical conductivity can be readily optimized by adjusting the Ni content in the cermets, and their corresponding maximum values reached 99.6%, 2.56 x 10(-11) g(2) cm(-4) s(-1) (at 800 degrees C) and 1.5 x 10(4) S cm(-1) (500 h oxidation reaction at 800 degrees C). Coefficient of thermal expansion could be adjusted as well in the 9.7 x 10(-6) k(-1) to 13.2 x 10(-6) k(-1) range to match with the IT-SOFCs components. The electrical conductivity of all samples studied in this work was above 1.0 x 10(4) S cm(-1), which is much higher than that of all other cermets reported in the literature. We demonstrated that TiN-Ni cermets are promising material as candidates for IT-SOFCs interconnects.
