In another aspect of the invention, the first solid electrolyte body is porous. In this case, the first and third electrodes are exposed to substantially the same atmosphere. In either case, the first and second, or third and fourth electrodes are disposed in alignment on opposite surfaces of the first or second solid electrolyte body. In the former case, the first and second cells serve as a pumping and sensing cell, respectively. In the latter case, the first and second cells serve as a sensing and a pumping cell, respectively.

    摘要： An electrochemical element includes a planar solid electrolyte body (2), and at least a pair of electrodes (4, 6) including a first electrode (4) and a second electrode (6) which are disposed on the planar solid electrolyte body (2). The element has a thin flat space (16,16) which has a predetermined diffusion resistance to a measurement gas and which communicates with an external space in which the measurement gas exists. The first electrode (4) is disposed so that it is substantially exposed to the measurement gas in the thin fiat space (16, 16). The element includes bridging members (3) interposed between two opposed flat surfaces (26, 28) which partially define the thin flat space (16,16). The bridging members (30) substantially determine the thickness of the thin flat space. The bridging members (30) may be formed by firing a mixture consisting of a filler material which disappears upon firing thereof, and ceramic grains. The mixture is applied in the form of a layer so as to occupy at least a portion of the thin flat space to be formed, and after firing, the ceramic grains form the bridging members (30).
