Abstract
Pt/ ZrO2-electrodes are used as sensitive layers in oxygen sensors. The low polarization resistances of the electrode are needed for good sensing properties. Barbucci et al. showed that the polarization resistance and the activation energy of the cermet electrode depend on the Pt content [1]. The aim of this work is to optimize the electrode microstructure to minimize the losses.
