摘要： A method of manufacturing an electrochemical device saving an electrochemical cell including a planar solid elec- rolyte body (2, 4) and at least two electrodes (10, 12) disposed in contact with the solid electrolyte body. So that the lectrochemical device does not suffer from warpage that vould arise due to difference in firing shrinkage between the layers, there is formed a first unfired ceramic layer (18) on one side of the unfired structure of the electrochemical cell 2,4,6), the first unfired ceramic layer being given a porous tructure by firing thereof, and a second unfired ceramic layer 20) on the other side of the unfired structure of the electro- hemical cell, the second unfired ceramic layer having sub- tantially the same property of firing shrinkage as the first nfired ceramic layer. The unfired structure of the electro- hemical cell, the first and second unfired ceramic layers is o-fired. The two unfired ceramic layers may be formed on pposite sides of an unfired structure of an electrochemical ell assembly which includes plural cells, for example, an xygen pumping cell and an oxygen sensing cell. In this case, nother unfired ceramic layer may be formed between the nfired structures of the two cells.

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 taht the electrodes are held in contact with the solid electrolyte bodies separately, at least one conductor sandwiched by two adjacent ones 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 with 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 a heater for heating a portion of the solid electrolyte body adjacent to the electrodes.

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.

摘要： The disclosed heater has a resistor (2) embedded in or tightly secured to a solid electrolyte (1). When an AC power source (4) is connected to the resistor (2), heat is generated both in the resistor (2) by alternating current, and in the solid electrolyte (1), because the resistor (2) heats the electrolyte (1), and increases its conductivity so that alternating current flows through the electrolyte (1) as well and heat is generated therein.

摘要： The disclosed oxygen concentration detector includes a plurality of resistive bodies (6, 7) at least one (7) of which forms an oxygen concentration cell, and means (14) for applying an alternating current of a specific frequency to a selected resistive body (6) via electrodes (10, 11) so as to raise the temperature thereof, said selected resistive body (6) being adapted to heat the oxygen concentration cell (7). The specific frequency is in a range such that the impedance of the body (6) is largely independent of the interface capacitance between the electrodes (10, 11) and the body (6). Also provided are a D.C. source (18) and means (19) for measuring the D.C. potential across the cell.

摘要： An oxygen concentration detector comprises an oxygen ion conductive solid electrolyte body (1) and electrodes (4, 5, 14) provided thereon to form an oxygen concentration cell for detecting oxygen partial pressure in a gas such as exhaust gas from an internal combustion engine. The oxygen concentration detector according to the invention further comprises an AC power source supplying to the electrodes (4,14) an AC current having a frequency at which a polarization of alternating current component is caused mainly due to a polarization of the solid electrolyte body to heat it, and a DC power source (11) supplying a direct current to the electrodes (4, 5) so as to control oxygen concentration on the side of at least one electrode of the oxygen concentration cell to detect its electromotive force.
