摘要：

A compact carbon dioxide gas sensor was fabricated using a trivalent Sc3+ ion-conducting Sc-2(WO4)(3) solid electrolyte and an oxide anion conducting stabilized zirconia. The time necessary to attain a 90% response for the CO2 detection was within 1 min. The output response was exactly equal to the Nernstian equation and the 1:1 linear relationship was obtained between the sensor output and the logarithm of the carbon dioxide gas content. A quantitative CO2 gas monitoring was successfully realized with a rapid, continuous, and reproducible response. (C) 1999 The Electrochemical Society. S1099-0062(99)05-102-0. All rights reserved.
