摘要： PURPOSE:To restrict the amount of oxygen contacting with a cathode and to lower the value of a thereshold electric current, by covering an electrode provided on both sides of an oxygen ion transmission body with a porous layer. CONSTITUTION:Heat-resistant electrode layers 2, 3 are formed on both sides of an oxygen ion transmission body 1 consisting of a solid electrolyte body formed a solid solution of ZrO2, HfO2 with a stabilizer such as CaO, MgO, Y2O3. The layers 2, 3 are covered by porous layers 4, 5 composed of a heat-resistant inorganic matter. The moving speed of oxygen is controlled by making the gas transmissivity of the layer 4 of a cathode 2 side smaller than that of the layer 5 of an anode 3 side. The gas transmissivity of the layers 4, 5 depends upon the diameter and density of fine holes and the thickness of the porous layer and 20-150mu thickness of the porous layer of the cathode 2 side and about 50:1-5,000:1 ratio of the layer thickness vs the diameter of the fine hole, are preferable. The gas transmissivity is enlarged by making the thickness of the layer 5 of the anode 3 side equal to or thinner than that of the layer 4 of the cathode 2 side or by enlarging the hole diameter.

摘要： PROBLEM TO BE SOLVED: To detect oxygen and nitrogen oxide gas with high precision and high sensitivity by providing an oxygen gas supplying part, an oxygen gas discharge part, and a measured gas detecting part on first, second, and third chambers, respectively. SOLUTION: A gas to be measured 17 diffused and carried into a first chamber 16 through a first port 15 is mixed with a fixed quantity of O2 gas supplied from an oxygen gas supplying part 6. The mixed gas is carried into a second chamber 21 through a second port 20.
