  abstract = {<p>The goal of this work is to identify suitable cathode contact materials (CCM) to bond and electrically connect LSCF cathode to Mn<sub>1.5</sub>Co<sub>1.5</sub>O<sub>4</sub>-coated 441 stainless steel after sintering at the relatively low temperature of 900–1000&nbsp;°C. A wide variety of CCM candidates are synthesized and characterized. For each, the conductivity, coefficient of thermal expansion, sintering behavior, and tendency to react with LSCF or Mn<sub>1.5</sub>Co<sub>1.5</sub>O<sub>4</sub> are determined. From this screening, LSCF, LSCuF, LSC, and SSC are selected as the most promising candidates. These compositions are applied to LSCF and Mn<sub>1.5</sub>Co<sub>1.5</sub>O<sub>4</sub>-coated 441 stainless steel coupons and subjected to 200&nbsp;h ASR testing at 800&nbsp;°C. After area-specific resistance testing, the specimens are cross-sectioned and analyzed for interdiffusion across the CCM/LSCF or CCM/Mn<sub>1.5</sub>Co<sub>1.5</sub>O<sub>4</sub> interfaces. A relatively narrow band of interdiffusion is observed.</p>},
