Abstract

Oxygen Charge transfer reaction has been investigated by various degrees of potential polarization at the Pt/YSZ interface. Anodic and cathodic charge transfer coefficients were found to be unity over the wide range of oxygen partial pressures and temperatures. While the exchange current density of the interface was found dependent on the partial pressure of oxygen in accordance with the relation: i 0=2FK r(K O 2 P O 2 ) 1/4 (1+K O 2 P O 2 ) 1/2 . Several important parameters, such as electrochemical rate constant, equilibrium constant of oxygen adsorption on Pt surface had also been extracted.

Keywords

Pt electrode, YSZ solid electrolyte, Oxygen charge transfer reaction.
