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.
