ABSTRACT:
An activated solid electrolyte oxygen gas sensing element with increased voltage output, shortened switching time and reduced internal resistance, the sensing element having inner and outer conductive catalyst electrodes thereon, is produced by subjecting the outer surface with the outer electrode to a nonoxidizing atmosphere and applying a direct current to the element while the same is at an elevated temperature, the current being applied with the outer electrode as an anode.
