ZrO2 Oxygen Sensor Because of the difficulty of gas diffusion in the electrode region, which leads to the increase of resistance and the increase of the transition process, a device for retarding the gas diffusion is produced in the cathode of the ZrO2 oxygen sensor. These phenomena are revealed and the mathematical simulation is performed. The proposed model is available To evaluate the condition and the degree of fouling of in-service ZrO2 oxygen sensor electrodes.
