使用烧结固体电解质和烧结体作为参比电极，建立了一种用于传感的新型固态电化学电池。电池的电动势（emf）、传感器信号的再现性和长期稳定性在干燥和潮湿条件下在300和300之间的温度下进行了检查。电动势取决于的分压，可以用能斯特方程表示。的灵敏度受到水蒸气的存在，但在潮湿的气体中的电动势响应也是能斯特的。电池在低至的温度下长期稳定，传感器信号可高精度再现。©1999电化学学会
A new solid‐state electrochemical cell for sensing has been set up using a sintered solid electrolyte and a sintered body as reference electrode. The electromotive force (emf) of the cell, the reproducibility and the long‐term stability of the sensor signals have been examined under both dry and humid conditions at temperatures between 300 and . The emf is dependent on the partial pressure of and can be expressed by the Nernst equation. The sensitivity to is affected by the presence of water vapor, but the emf response in humid gas is also Nernstian. The cell is long‐term stable at temperatures as low as and the sensor signals are reproducible with high accuracy. ©1999 The Electrochemical Society
