Controlling oxygen defect chemistry at electrolyte surface of intermediate temperature solid oxide fuel cells

Engineering the anion defect, especially oxygen vacancy, at the electrolyte surface is important because the concentration and distribution of defects at this surface often determine the oxygen reduction reaction (ORR) kinetics and, in turn, the electrochemical performance of intermediate temperatur...
