METHOD FOR TESTING AND/OR CALIBRATION OF AT LEAST ONE GAS CONCENTRATION SENSOR OF A FUEL CELL SYSTEM

摘要

The invention is based on a method for testing and / or calibrating at least one gas concentration sensor (38; 40; 42), in particular a hydrogen gas concentration sensor, which is used to monitor a gas concentration, in particular a hydrogen gas concentration, in an exhaust gas and / or a surrounding area (38; 46) of a fuel cell unit (12) is provided.;It is proposed that the gas concentration sensor (38; 40; 42) is tested and / or calibrated in at least one method step (160; 260) in a state in fluid communication with the fuel cell unit (12).
