Abstract
Solid oxide fuel cells (SOFCs) are provided. A SOFC may comprise a cathode, an anode, and a solid oxide electrolyte between the anode and the cathode, wherein the cathode comprises a perovskite compound. The perovskite compound may be characterized by a log k* value which is less negative than about −6.0 cm/s; an energy above the convex hull of less than about 40 meV/(formula unit); a bandgap of about 0 and a charge transfer gap of about 0.
