Abstract

A transmission line based model was successfully applied to study the ageing effect in LSM-YSZ cathodes after being exposed to humidified air at 900 °C for up to 3000 h. A decrease in the YSZ conductivity was correlated with the formation of the less conducting monoclinic zirconia. The amount of La2Zr2O7, present in the non-aged samples, decreases with ageing time increasing the number of active sites for charge transfer between LSM and YSZ as well as the LSM conductivity values.
