ABSTRACT:
A perovskite lanthanum gallate electrolyte doped with strontium and magnesium and a solid oxide fuel cell incorporating a doped lanthanum gallate electrolyte with a cathode on one side, an anode on the other side and a buffer layer comprising a mixed electronic and oxide-ion conductor between the anodes and/or the cathode and the electrolyte to block unwanted chemical reactions while permitting electronic and oxide-ion transport.
