Abstract: The characteristics of the CO gas sensor with partly Nafion solid electrolyte havebeen studied with the method of electrolysis at a fixed potential.It is found that the sensorhas the advantages of rapid response, low background current and noise etc.in comparisonwith that of the sensor using aqueous electrolyte.Hence, it may also be used for the measurement of low concentration CO gas.

Key words: carbon monoxide, Nafion membrane, gas sensor
