  • Cobalt-substituted perovskite compounds for solid oxide electrochemical cells
    Patent number: 11843123
    Abstract: Oxygen electrodes are provided, comprising a perovskite compound having Formula (I), Sr(Ti1-xFex-yCoy)O3-?wherein 0.90?x?0.40 and 0.02?y?0.30. Electrochemical devices comprising such oxygen electrodes are also provided, comprising a counter electrode in electrical communication with the oxygen electrode, and a solid oxide electrolyte between the oxygen electrode and the counter electrode. Methods of using such electrochemical devices are also provided, comprising exposing the oxygen electrode to a fluid comprising O2 under conditions to induce the reaction O2+4e??2O2?, or to a fluid comprising O2? under conditions to induce the reaction 2O2??O2+4e?.
