Abstract

PURPOSE: To lower the operating temperature of a gas detecting element by covering a solid electrolyte with a Pt electrode by the electron beam evacuation.
CONSTITUTION: An oxygen ion conductive solid electrolyte 11 made of ZrO2-Y2O3 has its both sides covered with an electrode 12 of Pt and an electrode 13 of Au, respectively. The gas detecting element thus prepared is held at a preset temperature by a heater 14 and is brought into contact with air 16 containing combustible gases so that the electromotive force established between the electrodes 12 and 13 is indicated by a meter 15. At this time, the Pt electrode 12 is coated by the electron beam evacuation so that the Pt is hardly crystallized but is firmly fixed to the electrolyte 11.
