ABSTRACT:
A fuel cell module includes a number of series-connected fuel cells which collectively form a fuel cell stack in such a way that the magnetic field or stray field that is generated during the operation of the fuel cell module and that is detectable in an outer area is kept particularly small. To this end, the invention provides that a number of shielding lines that are connected to a first pole flange of the fuel cell stack are provided, these shielding lines being guided on the outer area of the fuel cell stack, as far as a contact area to a second pole flange of the fuel cell stack.
