Abstract
A solid electrolyte-based sensor element of a gas sensor for determining a gas component in a gas mixture is described, in particular for determining the concentration of oxygen and/or nitrogen oxides in exhaust gases of internal combustion engines. The sensor element has an electrochemical cell that includes a first and a second electrode, both electrodes being located in internal gas spaces of the sensor element. The internal gas space in which the first electrode is located is largely in the same layer plane of the sensor element as at least one other internal gas space of the sensor element in which the second electrode or a reference electrode are located.
