Abstract

Abstract We report the optimization of the dopant concentration of gadolinia-doped ceria (GDC) to enhance the oxygen reduction reaction (ORR) kinetics for low-temperature solid oxide fuel cells (LTSOFCs). Crystalline {GDC} layers with uniform nano-granular structures were prepared by aerosol-assisted chemical vapor deposition (AACVD) on the cathode side of a {GDC} electrolyte. The current-voltage (I
