Abstract

A fuel cell module includes a plurality of fuel cells, which are connected one behind the other and which are combined to form a fuel cell stack. The fuel cell module should be designed in such a manner that the magnetic field or leakage field, which can be detected in the outer area and which is generated during the operation of the fuel cell module, is held at a particularly low level. To this end, the materials used for providing the fuel cells themselves, the materials used for producing the connecting components or auxiliary components, which are assigned thereto, that connect these fuel cells, and the materials used for producing the housing are selected that have a relative magnetic permeability of less than 1.1.
