Title:
GAS SENSOR ELEMENT
Document Type and Number:
Japanese Patent JP2018096951
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas sensor element capable of responding to a change in air-to-fuel ratio quickly and suppressing deterioration in detection accuracy of the air-to-fuel ratio.SOLUTION: A gas sensor element 100 comprises: a first solid electrolyte layer 12 including a first surface that is exposed to exhaust gas; a first electrode 11 provided on the first surface of the first solid electrolyte layer; a second electrode 13 provided on a second surface of the first solid electrolyte layer opposite the first surface; a second solid electrolyte layer 14 provided on the second surface of the first solid electrolyte layer; a third electrode 15 provided on a surface of the second solid electrolyte layer opposite the first solid electrolyte layer; a detection part 30 detecting current flowing between the first electrode and the second electrode; and a control part 40 flowing certain current between the second electrode and the third electrode.SELECTED DRAWING: Figure 1
