A novel symmetrical solid oxide electrolysis cell (S‐SOEC) utilizing a spinel structured MnCo 2 O 4 electrode is investigated for pure CO 2 electrolysis. The electrode is prepared through an impregnation method and is confirmed to have excellent performance for CO 2 electrolysis, with a current density of 0.75 A cm −2 at an applied voltage of 1.5 V at 800 °C. The MnCo 2 O 4 electrodes also show good stability for long‐term pure CO 2 electrolysis for more than 80 h. The study suggests that MnCo 2 O 4 is a potential electrode for pure CO 2 electrolysis in S‐SOECs.
