Abstract in another language

To detect NO in the low ppm range in exhaust gases is of high interest due to the ever tighter emission and immission regulations. Applying the pulsed polarization technique, Pt|YSZ sensors like the classical thimble type lambda probes for automotive applications or planar sensor elements (Pt electrodes on both sides of YSZ) show very good sensitivities toward NO. To further improve the sensor with respect to simplicity and robustness for exhaust gas applications, a one-sided design is preferred, especially to implement a heater on the reverse side of the sensor element. For that purpose, a design that bases on platinum interdigital electrodes is investigated. Again, by using this polarization technique very strong signals towards NO in the lowest ppm range have been achieved.
