Abstract
A carbon monoxide gas sensor is a single-chamber sensor for measuring the carbon monoxide gas concentration in a gas phase. The carbon monoxide gas sensor has electrodes disposed on respective sides of a solid electrolyte layer. One of the electrodes is active for oxidation of carbon monoxide gas, and the other of the electrodes is more inactive for oxidation of carbon monoxide gas than the one electrode. The carbon monoxide gas sensor is configured to measure a short-circuit current between the electrodes. In the carbon monoxide gas sensor, the solid electrolyte layer has oxide ion conductivity.
Claims8
A carbon monoxide gas sensor for measuring carbon monoxide gas concentration in a gas phase,
- the sensor comprising a single chamber sensor,
- the sensor comprising:
- an anion-conductive solid electrolyte layer;
- and
- a first electrode disposed on a first side of the solid electrolyte layer and a second electrode disposed on a second side of the solid electrolyte layer,
- wherein the first electrode is active for oxidation of carbon monoxide gas,
- the second electrode is more inactive for oxidation of carbon monoxide gas than the first electrode, and
- the carbon monoxide gas sensor is configured to measure a short-circuit current between the electrodes.
