The present study focuses on the highly catalytic double-perovskite Sr2FeMo0.65Ni0.35O6−δ (SFMNi) fuel electrode material for Solid Oxide Electrolysis Cells (SOECs). The electrolyte-supported single button cells with the highly active SFMNi fuel electrode were electrochemically characterized between 900 °C down to 750 °C in steam and co-electrolysis conditions using DC- and AC-techniques. The cells achieved current densities of −1.62 A cm−2 and −1.74 A cm−2 at 900 °C under steam and co-electrolysis conditions, respectively, exceeding the performance of cells with Ni-8YSZ fuel electrodes by ∼65–79 % and Ni-GDC fuel electrodes by 24–28 %. The post-test SEM-EDX analyses of the as-prepared and tested cells’ cross-section showed increased pore formation and particle growth of the SFMNi fuel electrode after testing in the humidified atmosphere for 500 h. |
