Procedure and device for the plausibility of a measured airmass flow in a fuel cell system cathode path

摘要

The invention concerns a procedure for the plausibility of a measured airmass flow in a cathode path (1) of a fuel cell system (2), covering the steps:-Production of a predefined operating condition of the fuel cell system (2), which is accompanied by a certain air mass flow and thus allows a certain measurement value to be expected,Measure the air mass flow using an air mass sensor (3); and-Comparison of the measured value with the expected measurement value.The invention also concerns a device for carrying out the inventive procedure.
