Abstract
A thin-film wide-range air-fuel ratio sensor has been fabricated on a porous alumina substrate. The sensor consisted of an oxygen pump cell and a limiting-current cell on the substrate. These cells were laminated in the order, Pt/ZrO2 electrolyte/Pt/ZrO2 electrolyte/Pt by sputtering technique. In this sensor, the oxygen pump cell served to supply oxygen to the limiting-current cell as substitution for air introduction. The limiting-current cell with a constant applied voltage of 0.6V showed a continuous output characteristic corresponding to air ratio of 0.7-1.5. The use of the oxygen pump cell has made it possible to eliminate air introduction and the changeover of the polarity of the applied voltage to the limiting-current cell.
