Thermal expansion and electrical conductivity of Fe and Cu doped MnCo2O4 spinel
Abstract
Manganese cobalt spinel oxides are promising coating materials for corrosion protection of metallic interconnects in solid oxide fuel cell stacks. This work investigates how Fe and Cu doping affect the crystal structure, thermal expansion and electrical conductivity of the MnCo<sub>2−x</sub>M<sub>x</sub>O<sub>4</sub> (M = Cu, Fe; x = 0.1, 0.3, 0.5) spinel oxides. Single phase cubic spinels were successfully prepared by spray pyrolysis. The electrical conductivity between room temperature and 1000 °C increased with addition of Cu and decreased with addition of Fe. The thermal expansion coefficient (TEC) between 50 and 800 °C decreased from 14.4 to 11.0 × 10<sup>−6</sup> K<sup>−1</sup> going from MnCo<sub>2</sub>O<sub>4</sub> to MnCo<sub>1.5</sub>Fe<sub>0.5</sub>O<sub>4</sub>. The TEC of the Cu substituted materials did not follow any obvious trend with composition and was likely influenced by precipitation of CuO during heating. Based on their physical properties, the Fe doped materials are the most attractive for application as SOFC interconnect coatings.
