ABSTRACT:
A gas sensor for determining a physical quantity of a gas component, e.g., in an exhaust gas of an internal combustion engine, including a sensor element which contains at least one electrochemical cell. The electrochemical cell includes a first electrode and a second electrode that are arranged at a distance on at least one solid electrolyte, the second electrode is arranged in a reference gas space. A third electrode which is in contact with a gas located in the gas space is provided. The gas component may be exchanged between the gas space and the reference gas space using a voltage applied between the second electrode and the third electrode.
