摘要： An apparatus for detecting at least one substance present in a fluid flow includes at least one field effect transistor which acts as a measuring sensor, and at least one field effect transistor which acts as a reference element, the field effect transistors each having at least one source electrode, one drain electrode, and one gate electrode. The gate electrode of the field effect transistor which acts as the measuring sensor is sensitive to the at least one substance to be detected, and the gate electrode of the field effect transistor which acts as the reference element is essentially insensitive to the at least one substance to be detected. The source electrode of one of the field effect transistors and the drain electrode of the other of the field effect transistors are connected to one another and to a signal line. A method for detecting at least one substance present in a fluid flow by using the apparatus is also described, a potential of 0 volt being applied to the signal line and the current flowing on the signal line being measured.

摘要： A sensor system for detecting a leak of a system component from an electrochemical storage system, in particular a lithium-ion battery. To determine a defect in the electrochemical storage system, the sensor system includes a reaction chamber containing a detection component, and a measuring device for determining a physical variable within the reaction chamber. The value of the physical variable is changeable by a chemical reaction of the system component with the detection component, so that a leak of the system component is detectable via a change in the value of the physical variable. Also described is a sensor element for such a sensor system, an electrochemical storage system having such a sensor system or sensor element, the use of such a sensor system or sensor element, and a mobile or stationary system, for example an electric vehicle, equipped with the sensor system, the sensor element, or the storage system.

A sensor element is used, having an oxygen reduction pumping cell for concentration of the gas species, a pumping cell connected downstream of the oxygen reduction pumping cell having pumping electrodes, and a gas-tight chamber. A pumping electrode may be exposed to gas from the measurement gas space which has been concentrated by the oxygen reduction pumping cell. A further pumping electrode is disposed in the gas-tight chamber. At least one measuring electrode is further disposed in the gas-tight chamber. The oxygen reduction pumping cell and the pumping cell are galvanically isolated. The method includes an initialization phase, and an accumulation phase.
