Abstract Zirconia doped with scandia and ceria (10Sc1CeSZ) is presented as an electrolyte in solid oxide electrolysis cells (SOECs) for hydrogen production at intermediate temperatures. At 700 °C, the conductivity of the 10Sc1CeSZ is 0.057 S cm −1 and the ohmic resistance at OCV is 0.27 Ω cm 2 . The electrolysis tests using Pt electrodes show that the oxygen ion conduction in the electrolyte produces high current densities when operating as a SOEC. The performance of cells with Ni-YSZ (yttria… CONTINUE READING
