Polarization resistance of PT/ZRO2-electrodes in dependence of the oxygen partial pressure: Poster at the 16th International Conference on Solid State Ionics, SSI-16. 1-6 July, 2007, Shanghai Worldfield Convention Hotel, Shanghai, China

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
