Abstract

In order to improve the stability of a NASICON (Na3Zr 2Si2PO12; Na+ conductor)-based potentiometric CO2 sensor under humid conditions, a new solid-reference electrode of the BiCuVOx (Bi2Cu0.1V 0.9O5.35)/perovskite-type oxide (La0.6Sr 0.4Co0.02Ni0.02Fe0.2O3) composite was investigated. The fabricated electrochemical cell (CO 2+O2, Au/ Li2CO3-BaCO3/ NASICON/ BiCuVOx-La0.6Sr0.4Co0.78Ni 0.02Fe0.2O3, O2) responded well to changes in CO2 concentration (100-400 ppm) at 400-450 °C under high humid conditions (86 %RH) without degradation. The sensor device also exhibited a good warming-up characteristic, i.e., the electromotive force of the device quickly reached a steady and constant value when the sensor operation is re-started even after the sensor was exposed to high humid air at room temperature.
