ABSTRACT:
An electrochemical sensor, in particular for determining the oxygen content in exhaust gases of internal combustion engines, has a solid electrolyte element having at least one first electrode, at least one second electrode, and at least one heating element. The second electrode located to the heating element is connected to ground, and the first electrode coacting with the second electrode is negatively polarized, a negative operating voltage being provided.
