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.
