Impedance measurements performed on LSM/YSZ cathodes at different thicknesses were carried out to investigate on the distribution of the active sites within the electrodes. Results show a remarkable effect of the electrode thickness on the overall reaction rate in all the temperature range. A simplified theoretical model of the electrode was developed. The model simulation compared satisfactorily with the experimental data

Abstract
Impedance measurements performed on LSM/YSZ cathodes at different thicknesses were carried out to investigate on the distribution of the active sites within the electrodes. Results show a remarkable effect of the electrode thickness on the overall reaction rate in all the temperature range. A simplified theoretical model of the electrode was developed. The model simulation compared satisfactorily with the experimental data
