The authors present the sensing characteristics of a selective high-temperature YSZ-based H2 sensor, with low sensitivity towards the following interfering gases: CO, CH4, C3H6, C3H8, NO, NO2 and NH3. The developed H2 sensor was highly sensitive with a lower detection limit of 10 ppm under standard atmospheric conditions (21 vol.% O2, _32% RH at 25°C), making it an interesting potential candidate for environmental or safety monitoring applications. The fabricated sensor utilizes an Au mesh over the Pt sensing electrode to augment H2 sensitivity; this enhancement will be discussed with respect to sensing electrode composition.
