ABSTRACT:
An electrochemical device having a sensing cell and a pumping cell. The sensing cell includes: a first planar solid electrolyte body; a first and a second porous electrode disposed on the first planar solid electrolyte body, the second electrode being exposed to a reference gas which has a predetermined oxygen partial pressure; and a diffusion resistance member which has a predetermined diffusion resistance to a measurement gas and covers the first electrode. An electric current is applied between the first and second electrodes, such that the electric current flows from the first electrode to the second electrode to induce an electrode reaction for controlling an atmosphere adjacent to the first electrode. The pumping cell includes: a second planar solid electrolyte body; a third and a fourth electrode of a porous structure disposed on the second planar solid electrolyte body. The third electrode is exposed to the reference gas to which the second electrode is exposed, and the fourth electrode is exposed to the measurement gas. An electric current is applied to flow from the third electrode to the fourth electrode, whereby an oxygen component of the measurement gas moves into the reference gas.
