摘要： A sensor element of a gas sensor is described, this sensor being used to determine the concentration of at least one component of a gas mixture, in particular in exhaust gases of internal combustion engines. It includes at least two electrodes which are situated in an internal gas space which is in direct contact with the gas mixture, the one electrode containing a first material and the second electrode containing a second material. The internal gas space contains a means which acts physically and/or chemically to prevent diffusion of metal between the electrodes.

摘要： A sensor for determining gas components and concentrations in a gas mixture that is particularly suitable for analyzing HC, NOx and CO in exhaust gases of internal combustion engines in the sensor, an outer electrode, that is separated from an MOx electrode by an electrolyte layer, is applied on a substrate. In this context, the outer electrode and the MOx electrode are in communication with the gas mixture to be analyzed. In addition, the outer electrode contains a region that is in contact with a gas-permeable tunnel layer which in turn contains a region that is directly exposed to the gas mixture to be analyzed, so that the gas to be analyzed can be supplied to the outer electrode via the gas-permeable tunnel layer.

摘要： A sensor element is provided for gas sensors, in particular to determine particles in gas mixtures, the sensor element including at least one electrochemical measuring element exposed to the gas mixture to be determined, and at least one temperature-measuring element integrated into the sensor element. The temperature-measuring element includes a resistor track, which has an electric resistance of less than 180 Ohm at 0° C. The resistor track may thus be produced by thin-foil technology, such as screen printing, for example.
