A gas sensor and a process are provided for manufacturing a gas sensor with an oxygen ion-conducting solid electrolyte, which has a measurement gas side and a reference gas side and which separates a measurement gas space from a reference gas space, at least one measurement electrode being arranged on the measurement gas side of the solid electrolyte and at least one reference electrode being arranged on the reference gas side of the solid electrolyte, and with a support which is gas-permeable at least in the area of the electrodes. The problem presents itself of providing an economical gas sensor, in which the gas supply to the electrodes takes place through a gas-permeable support, as well as providing a simple process for manufacturing the gas sensor. The problem is solved for the gas sensor in that the oxygen ion-conducting solid electrolyte and the electrodes are constructed as thin layers and are arranged on the gas-permeable support.
A gas sensor comprising an oxygen ion-conducting solid electrolyte, having a measurement gas side and a reference gas side, the solid electrolyte separating a measurement gas space from a reference gas space, at least one measurement electrode arranged on the measurement gas side of the solid electrolyte, at least one reference electrode arranged on the reference gas side of the solid electrolyte, and a support which is gas-permeable at least in a region of the electrodes, wherein the oxygen ion-conducting solid electrolyte and the electrodes are constructed as thin layers and are arranged on the gas-permeable support.
