1. A device (1) with at least one fuel cell (2) and a DC/DC converter (3) assigned thereto, wherein a variable voltage generated in the fuel cell (2) is converted into a DC voltage by means of a DC/DC converter (3) for a system (4) to be supplied, characterized in that the DC/DC converter (3) is designed to capture internal characteristic variables of the fuel cell (2), wherein operating states of the fuel cell (2) are captured and/or controlled in dependence on these characteristic variables, wherein a regenerative operating state of the fuel cell (2) is achieved by operating it for a short time at excessive current and therefore, reduced voltage.
