Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.
