Abstract

A sensor element of a gas sensor for determining gas components in gas mixtures, having at least one electrochemical measuring cell which is formed by a ceramic substrate and electrodes placed thereon. The sensor element includes at least one interior chamber which is sealed in a gas-tight manner, in which at least one first internal electrode is positioned, which forms an electrochemical cell with each of a second and an additional electrode of the sensor element, one of the electrochemical cells being an electrochemical pump cell, and the second or other electrode being exposed to the measuring gas.
