Abstract

The ionic current-overpotential characteristics of cathodes on ceria-based electrolytes have been evaluated by galvanostatic current-interruption measurements under fuel cell operating conditions. The effect of either mixed ionic electronic conductivity or high oxygen diffusivity on the oxygen reduction kinetics was investigated. La_0.8Sr_0.2MnO₃ served as a model substance for cathodes with a high activity for oxygen reduction and a low oxygen ionic conductivity. The behaviour of La_0.8Sr_0.2MnO₃ is compared to that of La_0.84Sr_0.16CoO₃ which shows high activity for oxygen reduction and high oxygen diffusivity.
