| description | To provide a gas sensor and a manufacturing method therefor with which it is possible to measure the concentrations of a plurality of gas components in gas to be measured, even when an oxygen concentration in the gas to be measured increases.SOLUTION: A gas sensor 10 comprises a structure 14 composed of an oxygen ion conductive solid electrolyte, a gas introduction port 16 formed in the structure 14, a reserved vacant chamber 21 communicating with the gas introduction port 16 and provided with a reserved pump electrode 82, a main vacant chamber 18a communicating with the reserved vacant chamber 21 and provided with a main pump electrode 42, and a measurement vacant chamber 20 communicating with the main vacant chamber 18a and provided with a measurement electrode 62. At least the surface of the reserved pump electrode 82 is formed with a material whose activity to reaction with ammonia and oxygen is low.SELECTED DRAWING: Figure 2
【課題】被測定ガス中の酸素濃度が増加した場合であっても、被測定ガス中の複数のガス成分の濃度を測定できるガスセンサ及びその製造方法を提供する。【解決手段】酸素イオン導伝性の固体電解質からなる構造体１４と、構造体１４に形成されたガス導入口１６と、ガス導入口１６に連通し、予備ポンプ電極８２を備えた予備空室２１と、予備空室２１に連通し主ポンプ電極４２を備えた主空室１８ａと、主空室１８ａに連通し測定電極６２を備えた測定空室２０と有するガスセンサ１０において、予備ポンプ電極８２の少なくとも表面が、アンモニアと酸素との反応に対する活性の低い材料で形成されてなるガスセンサ１０が提供される。【選択図】図２ |
