摘要： A gas sensor having a laminate structure composed of thin sheets of solid electrolyte and including a cavity portion 21 and an oxygen concentration cell 5. The oxygen concentration in the cavity portion 21 is held constant. The oxygen concentration cell 5 includes an active electrode 12 having a relatively high catalytic capability with respect to NOx or combustible gas and an inner common electrode 13/15 (serving as an inactive electrode and an oxygen-concentration-sensing electrode) having a relatively low catalytic capability with respect to NOx or combustible gas. The oxygen concentration cell 5 is disposed in the gas sensor so as to be exposed to the interior of the cavity portion 21. The concentration of NOx or combustible gas is determined based on an electromotive force (of the order of mV) generated between the active electrode 12 and the inner common electrode 13/15 by a concentration cell effect.

摘要： An apparatus and method using a two-serial space sensor (having first and second internal spaces 2,3) for accurately measuring NOx concentration in gas, e.g., exhausted from an internal combustion engine. Both NOx (nitrogen oxide) and oxygen are forced to be partially dissociated in the first space 2 to an oxygen concentration level of 2×10−7 to 2×10−10 atm by pumping out oxygen from the first space 2. The NOx concentration is determined based on the second current measured in the second space 4 and based on the NO dissociation percentage in the first chamber which is 0.5-50%, or preferably 2-20%. The NOx measurement accuracy is further improved when the above oxygen concentration level is maintained from 2×10−8 to 2×10−9 and the temperature drift of the sensor is maintained within ±5° C. under a sensor temperature range of 700-900° C.
