A zirconia-based electrochemical device attached with an oxide electrode was developed for the detection of H{sub 2} in air at elevated temperature. The sensing mechanism was confirmed to involve a mixed potential at the oxide sensing electrode. Among the oxides tested, ZnO was the best suited for the sensing electrode, giving a sharp selective response to 50--500 ppm H{sub 2} in air at 450 to 600 C.
