The oxygen evolution reaction (OER) at Teflon-bonded Ti/Co(3)O(4) electrodes was investigated and the process was simulated using an equivalent circuit fitting method and a mathematical model based on the Faradaic impedance of the reacting system. The correlation between the auxiliary electrochemical parameters and the elements of the equivalent circuit was derived and the lumped kinetic parameters of the different steps involved during oxygen evolution were evaluated. The method was validated by comparing experimental and model predicted data.

Abstract
The oxygen evolution reaction (OER) at Teflon-bonded Ti/Co(3)O(4) electrodes was investigated and the process was simulated using an equivalent circuit fitting method and a mathematical model based on the Faradaic impedance of the reacting system. The correlation between the auxiliary electrochemical parameters and the elements of the equivalent circuit was derived and the lumped kinetic parameters of the different steps involved during oxygen evolution were evaluated. The method was validated by comparing experimental and model predicted data.
