Title:
CARBON MONOXIDE GAS SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/270448
Kind Code:
A1
Abstract:
This carbon monoxide gas sensor 10 is a single chamber sensor for measuring the concentration of gaseous-phase carbon monoxide gas. The carbon monoxide gas sensor 10 has electrodes 12, 13 respectively arranged on the two surfaces of a solid electrolyte layer 11. One electrode among the electrodes is active for oxidization of carbon monoxide gas and the other electrode among the electrodes is less active for oxidization of carbon monoxide gas than the one electrode. The carbon monoxide gas sensor 10 is configured to measure a short circuit current between the electrodes. In the carbon monoxide gas sensor 10, the solid electrolyte layer has oxide ion conductivity.
