Cobalt-substituted perovskite compounds for solid oxide electrochemical cells
Abstract
Oxygen electrodes are provided, comprising a perovskite compound having Formula (I), Sr(Ti1-xFex-yCoy)O3-δ 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−.
