Thickness Dependence of Oxygen Reduction Reaction Kinetics on Strontium-Substituted Lanthanum Manganese Perovskite Thin-Film Microelectrodes

Thickness Dependence of Oxygen Reduction Reaction Kinetics on Strontium-Substituted Lanthanum Manganese Perovskite Thin-Film Microelectrodes

Oxygen reduction reaction (ORR) kinetics was investigated on dense La₀.₈Sr₀.₂MnO₃ microelectrodes as a function of temperature and microelectrode thickness using electrochemical impedance spectroscopy. The surface oxygen exchange and mixed bulk/three-phase-boundary (TPB) charge transfer process were...
