Abstract

A sensor unit (20) for an air filter (1) configured to separate, from an air flow (3), at least one harmful gas, in particular for a fuel cell (2), the sensor unit (20) comprising a first sensor (21) and a second sensor (22), each of which comprising two electrodes (27, 28) and a material layer (30) connecting the two electrodes (27, 28), an electrical resistance of the material layer (30) changing when the material layer (30) comes into contact with the harmful gas, and the material layer (30) of the first sensor (21) being different from the material layer (30) of the second sensor (22), and a processing unit (23) configured to determine a time derivative of a change in the electrical resistance of the material layer (30) of at least the first sensor (21), and to generate an output signal (26) based on the determined time derivative.
