摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas sensor which can selectively detect a specific hydrocarbon component and obtain information related to concentrations of different components or component groups separately. SOLUTION: Two elements 3, 4, one functioning as an oxygen concentration cell element and the other functioning as an oxygen pump element, are set to face each other via a gap 15. Electrodes 10-13 of different oxidation catalyst activation differences are arranged at both faces of each element 3, 4. An exhaust gas is introduced to both sides of the element functioning as the oxygen concentration cell element. A difference of oxygen consumption amounts is brought about at both sides of the oxygen concentration cell element due to oxidation (burning) of a component to be detected of the exhaust gas, whereby a concentration cell electromotive force is generated. The element functioning as the oxygen pump element sucks in or out the oxygen to the gap so as to make the concentration cell electromotive force constant. A concentration of the component to be detected in the exhaust gas is detected from a current value of the oxygen pump.

摘要： PROBLEM TO BE SOLVED: To accurately detect the concentration of component to be detected in a gas even when the oxygen concentration in an exhaust gas is changed. SOLUTION: An exhaust gas sensor 1 used for a measuring device is adjusted in a manner that, after an exhaust gas is introduced to the clearances 15 and 16 on both the sides of an oxygen concentration cell element 4, activation of first to third electrodes 11 to 13 as an oxidizing catalyst may cause a difference in consumption quantity due to oxidization of components to be detected between the clearance 15 side and clearance 16 side. Thus, an electromotive force for concentration cell is generated in the element 4, and an oxygen pump element 3 fills or draws an oxygen in/from the clearance 15 as to keep the electromotive force to be a target value EC of at most 10mV. The pump current at this time is picked up as a detection output to component to be detected. Then, the detection accuracy of component to be detected is improved by controlling the temperature of the element 4 and performing temperature compensation to the pump current as well.

摘要： PROBLEM TO BE SOLVED: To enable highly accurate detection of the concentration of a combustible material by providing a concentration of oxygen measuring cell and an oxygen pumping cell on differ ent solid electrolytic layers to enhance the measuring accuracy of the concentration of oxygen. SOLUTION: Oxygen is sampled 6 monitoring the concentration of oxygen in a gap part 2 by a concentration of oxygen measuring cell 7 to be controlled to a low concentration of the oxygen to such an extent that no combustible material in the gap part 2 will be decomposed by combustion. The combustible material in the gas to be measured consumes only a slight amount of oxygen in the gap part 2 when burned on a porous electrode. The change in the oxygen is detected 7 and the oxygen is sucked 6 to be maintained at a specified concentration of the oxygen. The gas to be measured is sent to the gap part 4 via a diffusion path 3 and the oxygen is drawn outside by an oxygen pumping 8. The amount of the oxygen is measured from the value of a current flowing through the cell 8 to calculate the concentration of the combustible material. In this process, as the cells 7 and 8 are installed on different electrolytic layers 5-3 and 5-6 , leakage current is very limited to enhance the measuring accuracy of the concentration of the oxygen. This enables accurately controlling of the concentration of the oxygen at the gap part 2 thereby detecting the concentration of the combustible material at a high accuracy.

摘要： PROBLEM TO BE SOLVED: To provide: an abnormality detection device of a steam sensor for a fuel cell, which can suitably perform abnormal diagnosis of the steam sensor; a steam sensor for the fuel cell; and a fuel cell system.
SOLUTION: Impedance (Rpvs) between both porous electrodes 45, 47 of a reference cell 33 is measured at the same timing with measurement of impedance of a pump cell 31 during an operation of the fuel cell system 1, and the impedance of the pump cell 31 and the impedance of the reference cell 33 are compared with each other. For example, it can be determined whether or not abnormality occurs on the pump cell 31 by comparing a ratio of both impedance when both the pump cell 31 and the reference cell 33 are normal by picking up its ratio H (=Rpvp/Rpvs). That is, when the ratio H of the impedance is deviated from a range of normal values, it can be determined that any abnormality occurs on the pump cell 31.
