摘要： PROBLEM TO BE SOLVED: To provide a method for accurately measuring the concentration of nitrogen oxide in the gas to be measured and a nitrogen oxide concentration detector. SOLUTION: The gas to be measured containing oxygen and nitrogen oxide is diffused in a first chamber 1 to which a first pump cell 6 faces and succeedingly diffused in a second chamber 4 to which a second pump cell 8 faces. The first pump cell 6 dissociates O2 and NO in the first chamber 2 to pump generated oxygen ions out of the chamber 2 and controls the concentration of oxygen in the gas coming into contact with the second pump cell 8 so as to lower the same to the utmost. The second pump cell 8 dissociated residual NO diffused in the second chamber 4 to pump generated oxygen ions out of the chamber. On the basis of the current flowing by the ion conduction of oxygen introduced into and led out of the first and second chambers through solid electrolyte layers 5-1, 5-5 by the first and second pump cells 6, 8, the concentration of nitrogen oxide is calculated in consideration of the influence of NO dissociation in the first chamber 2.

摘要： PROBLEM TO BE SOLVED: To detect the nitrogen oxide concentration in a measured gas with high accuracy by providing the first oxygen pumping cell, an oxygen concentration measuring cell, and the second oxygen pumping cell on different solid electrolyte layers respectively. SOLUTION: In this nitrogen oxide concentration detector, the first oxygen pumping cell 6, an oxygen concentration measuring cell 7, and the second oxygen pumping cell 8 are provided on different solid electrolyte layers 5-2, 5-3, 5-4 respectively. The current leak between the electrodes of the oxygen cells 6, 7, 8 becomes slight, and the accuracy of the oxygen concentration measured by the cell 7 is high. Oxygen is extracted from the first void section 2 with the cell 6 while the oxygen concentration in the first void section 2 is monitored with the cell 7, and the oxygen concentration in the first void section 2 is controlled at the low oxygen concentration that a nitrogen oxide is not decomposed practically. Since the oxygen concentration in the first void section 2 can be stably controlled at low oxygen concentration, the nitrogen oxide concentration in the measured gas having low nitrogen oxide concentration can be detected with high accuracy.
