Pt-Oxide Coverage-Dependent Oxygen Reduction Reaction (ORR) Kinetics

Oxygen Reduction Reaction (ORR) currents have been measured under the potential range of an operating fuel cell (0.72-0.9 Volts) while keeping proton and oxygen transport-related overpotentials insignificant by testing with pure O2, at 100%RH and at low current densities. Low potential points are ac...

Zusammenfassung:Oxygen Reduction Reaction (ORR) currents have been measured under the potential range of an operating fuel cell (0.72-0.9 Volts) while keeping proton and oxygen transport-related overpotentials insignificant by testing with pure O2, at 100%RH and at low current densities. Low potential points are achieved by reducing the platinum loading on the cathode and operating under sub-ambient (
