  • Patent number: 9121819
    Abstract: A gas sensor including an internal space, a first electrode, a second electrode, a pumping cell, a third electrode, a fourth electrode, a measuring cell, and a porous diffusion layer. The first and third electrodes, and the second and fourth electrodes are formed inside and outside the internal space, respectively. The pumping cell includes the first and second electrodes, and the measuring cell includes the third and fourth electrodes. The pumping cell pumps oxygen from the internal space when a predetermined voltage is applied between the first and second electrodes. The third electrode reduces an oxide gas component in a predetermined gas component to which a predetermined diffusion resistance has been applied by the porous diffusion layer. The measuring cell measures current flow between the third and fourth electrodes when a voltage corresponding to the degree of reduction in the third electrode is applied between the third and fourth electrodes.

  • Patent number: 9091646
    Abstract: A NOx sensor 100 includes a sensor device 110 and a heater 70 capable of heating the sensor device 110. The sensor device 110 includes an inner pump electrode 22 and an outer pump electrode 23 disposed respectively on the inner side and the outer side of a solid electrolyte layer 6. The sensor device 110 detects the concentration of NOx by introducing a gas to be measured into a first inner vacancy 20, pumping out oxygen in the gas to be measured from the inner pump electrode 22 to the outer pump electrode 23, introducing the gas to be measured, from which the oxygen has been pumped out, into a second inner vacancy 40, reducing the NOx in the gas to be measured, to thereby generate oxygen, and detecting the generated oxygen. A characteristic stabilizing layer 24 covers the outer pump electrode 23 and is made of a porous body with a thickness of 10 to 200 ?m and a thickness variation of 20% or less.
