摘要：

This paper reports the effect of the sensitive layer thickness on the response of Nasicon based electrochemical CO2 sensors. It was found that: (a) the cell voltage dependence on the thickness of the thin film Na2CO3 auxiliary electrode is well described within the theory of Schottky barriers formation in ionic crystals; and (b) sensors with relatively thick gas-sensitive layer are more reliable in dry CO2 atmosphere.
