- 摘要:
- An yttria-stabilized cubic zirconia (YSZ) based mixed-potential sensor coupled with CoWO4 as the sensing electrode was developed for hydrogen detection at elevated temperatures. The developed CoWO4/YSZ/Pt sensor was found to have a good sensitivity to different concentrations of hydrogen from 80 ppm to 960 ppm in a background of 10% O-2/N-2 at 450 degrees C. The sensor showed excellent selectivity to several possible interferents such as CO, C3H8 and NO2. The reproducibility and signal repeatability of the sensor was examined to test the reliability of the sensor. The influence of oxygen variation and humidity in the background on the sensor response was also studied.
