PROBLEM TO BE SOLVED: To provide a sensor system for detecting a relative humidity level of a gas flow in a fuel cell. SOLUTION: The sensor system includes a humidity sensor, which detects the relative humidity of the gas flow and generates a relative humidity signal. A pressure sensor detects the pressure of the gas flow and generates a pressure signal. A temperature sensor detects the temperature of the gas flow and generates a temperature signal. The humidity sensor, the temperature sensor and/or the pressure sensor is connected with a compensation device. The compensation device generates a compensated relative humidity signal, based on the relative humidity signal, the temperature signal and/or pressure signal. The compensation device additionally includes input from one or more gas composition sensors that determine the concentration of one or more gases. |
