摘要： An electrochemical device such as an oxygen sensor comprising: a plurality of solid electrolyte bodies; at least one pair of electrodes, each pair being disposed such that the electrodes are held in contact with the solid electrolyte bodies separately; at least one conductor sandwiched by two adjacent conductors of the solid electrolyte bodies; and at least one electrical insulation layer. A substantive portion of at least one side of the conductor indirectly contacts one of the two adjacent solid electrolyte bodies via the electrical insulation layer which is disposed therebetween, whereby the conductor is protected from direct contact with the associated solid electrolyte body. The insulation layer further serves to prevent noises which could otherwise be produced due to leakage current from the conductor. The conductor may be a lead connected to one of the electrodes, or to a heater for heating a portion of the solid electrolyte body adjacent the electrodes.

摘要： A method of manufacturing an electrochemical device having an electrochemical cell including a planar solid electrolyte body and at least two electrodes disposed in contact with the solid electrolyte body. The method comprising: forming a first unfired ceramic layer on one side of an unfired structure of the electrochemical cell, the first unfired ceramic layer being given a porous structure by firing thereof; forming a second unfired ceramic layer on the other side of the unfired structure of the electrochemical cell, the second unfired ceramic layer having substantially the same property of firing shrinkage as the first unfired ceramic layer; and co-firing the unfired structure of the electrochemical cell, the first and second unfired ceramic layers. The two unfired ceramic layers may be formed on opposite sides of an unfired structure of an electrochemical cell assembly which includes plural cells, for example, an oxygen pumping cell and an oxygen sensing cell. In this case, another unfired ceramic layer may be formed between the unfired structures of the two cells. The electrochemical device manufactured by the method does not have a unfavorable warpage that would arise due to difference in firing shrinkage between the layers.

摘要： An electrochemical device for dealing with a measurement gas in an external measurement-gas space, including an electrochemical sensing element having a pumping cell and a sensing cell. The pumping cell has a first planar solid electrolyte body, and a first and a second electrode disposed on corresponding areas of opposite surfaces of the first solid electrolyte body. The sensing cell has a second planar solid electrolyte body, and a third and a fourth electrode disposed on the second solid electrolyte body. The sensing element has an internal measurement-gas space communicating with the external measurement-gas space, so that the measurement gas is introduced into the internal measurement-gas space with a predetermined diffusion resistance. The first and third electrodes are substantially exposed to the internal measurement-gas space. A reference gas is accommodated in a reference-gas space to which the second and fourth electrodes are substantially exposed to the reference-gas space. Thus, none of the electrodes are directly exposed to the external measurement-gas space.

摘要： An electrochemical device comprising at least one electrochemical cell having a planar solid electrolyte body, and a first and a second electrode one of which is disposed on the solid electrolyte body. The device has a measurement-gas space communicating with an outside space for introducing a measurement gas, and a reference-gas space into which a reference gas is introduced. The first and second electrodes are exposed to the measurement-gas and reference-gas spaces, respectively. The measurement gas is introduced into the measurement-gas space with a diffusion resistance to molecules of a selected component of the measurement gas. The measurement-gas and reference-gas spaces are juxtaposed in spaced-apart relation with each other in substantially the same plane parallel to the planar solid electrolyte body. The device may include two electrochemical cells, one serving as a sensing cell having said first and second electrodes, and the other serving as a pumping cell having two electrodes one of which is exposed to the measurement-gas space. A heating layer may be disposed on the side of the sensing cell. In this case, the first and second electrodes are spaced from each other in the direction parallel to the solid electrolyte body.
