Electrically-conductive spinels have been extensively studied as the interconnect coating material for solid oxide fuel cell (SOFC). Furthermore, they are also being considered for the SOFC cathode-interconnect contact application. This presentation will report the sintering behaviours of several spinels with metallic precursor powders. The precursor powders are screen printed onto the Crofer 22 APU interconnect substrate, followed by sintering in air to achieve a spinel-based contact layer. The phase purity and microstructure of the sintered layers are characterized with X-ray diffraction, optical microscopy, and scanning electron microscopy. In addition, the area-specific resistance and mechanical bond strength of the sintered layers in an interconnect/spinel layer/cathode assembly is experimentally determined. The factors affecting the spinel formation via reactive synthesis with metallic precursor powders are analyzed and the underlying mechanism is elucidated.
