Abstract

The invention relates to a contact module (14, 14a, 14b, 14c) for monitoring a substack (18, 18a, 18b, 18c) of bipolar plates (4, 4a, 4b, 4c) of a fuel cell stack (10) that are stacked on top of one another in a stacking direction (6), with a plate contacting assembly (20) which is configured to electrically contact the bipolar plates of the substack, and with a measuring device (24) which is electrically connected to the plate contacting assembly and is configured to measure a differential voltage (28) between each two neighboring bipolar plates of the substack and generate a voltage signal (70) that is representative of this differential voltage. The object of the invention also includes a set of such contact modules as well as a fuel cell system with such a set of contact modules. The cell voltages of a fuel cell stack can be measured precisely with the devices according to the invention. At the same time, a complex structure of the devices according to the invention is prevented.
