【Abstract】 Direct synthesis method was used to prepare CaZr0.9In0.1O3-a. The complex impedance measurement shows that the conductivity of this electrolyte was 10-4￣10-2scm-1 at the range of temperature 8691300 K in air. The hydrogen probe was made by using. CaZr0.9In0.1O3-a as solid electrolyte,standard H2 mixture gases as reference electrode. Galvanic cell used could be expressed as Fe,standard H2 CaZr0.9In0.1O3-a[H]Al,Fe. The experiments show that the H2 sensor exhibits stable electromotive force and fast response time.更多还原
