Abstract
An electrochemical gas sensor for determining the concentration of gas components in a gas mixture, in particular for determining NOx and HC. The gas sensor includes a first measuring gas space which is connected to the measuring gas, and a second measuring gas space which is connected to the first measuring gas space by a connecting channel. Furthermore, a first electrode and a second electrode, arranged in the first measuring gas space, and at least one third electrode arranged in the second measuring gas space, and at least one fourth electrode are provided. The two measuring gas spaces are arranged in layer planes on top of one another and are separated from one another by at least one oxygen ion conducting layer, the connecting channel passing through the oxygen ion conducting layer.
