Thermodynamic modeling of the Co-Fe-O system

► The Co-Fe-O was modeled as a subsystem of La-Sr-Fe-Co-O for applications in SOFCs. ► The modeling covers a temperature range of 298-3000 K and PO2 range of 10−16-102 bar. ► A good agreement between the calculation and experimental results was achieved. ► Improvements were made compared with previous modeling results.
