摘要：

A zirconia-based electrochemical device attached with an oxide electrode was developed for the detection of H-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 similar to 500 ppm H-2 in air at 450 to 600 degrees C.
