Abstract: The invention relates to an EMC filter for a control device. The filter includes a multilayer circuit carrier comprising electrically conductive layers, in particular copper layers, and electrically insulating circuit board layers. According to the invention, the circuit carrier of the aforementioned type forms at least two filter capacitors, wherein in each case the filter capacitors are formed by electrically conductive layers that are formed in the circuit carrier and lie across from one another and/or extend parallel at a distance from each other.

Abstract: A fuel cell system has a fuel cell unit for generating electric current and/or thermal heat, a cooling device provided for cooling the fuel cell unit and having at least one first flow generator for generating a flow of a first cooling fluid, in particular a liquid coolant, and a second flow generator for generating a flow of a second cooling fluid, in particular a cooling air, in which a more-efficient temperature regulation is realized, compared to the prior art, with a control unit provided for comparison of a first operating parameter, or a change in the first operating parameter, of the first flow generator with a second operating parameter, or a change in the second operating parameter, of the second flow generator.
