A solid oxide fuel cell is provided having a ceria-based bulk electrolyte layer, an interface layer, an anode and a cathode, where the ceria-based bulk electrolyte layer is disposed between the cathode and the interface layer, and the interface layer is disposed between the ceria-based bulk electrolyte layer and the anode. Use of the ceria-based bulk electrolyte layer and an interface layer between the bulk layer and the anode takes advantage of the properties of a Ceria-based electrolyte without reducing to Ce (III) when operating the SOFC at the prescribed temperatures. The ceria-based bulk electrolyte layer has a thickness in a range of 10 nm to 500 um, and the interface layer has a thickness in a range of 1 angstrom to 50 nm.
