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