Abstract
The manganese tangstenates (MnWO4) was explored for the first time for the oxide sensing electrode of the yttria-stabilized zirconia electrolyte (YSZ) based mixed-potential type sensor for detecting hydrogen at elevated temperatures. The MnWO4/YSZ/Pt sensor was found to have a good sensitivity to different concentrations of hydrogen from 80 ppm to 960 ppm in the background of 10% O2/N2 at 500 °C. The sensor also indicated excellent selectivity to several possible interferents such as CO, C3H6, C3H8 and NO2. The reproducibility and signal repeatability of the sensor and humidity influence were also studied.
