Abstract

The invention relates to a fuel cell system () comprising: at least one fuel cell () which has a cathode () with a cathode chamber and has an anode chamber of an anode (), which anode chamber is separated from the cathode chamber by a membrane, wherein the cathode chamber is connected to a cathode gas source via at least one first fluid connection () and the anode chamber is connected to an anode gas source via at least one second fluid connection; and comprising a first electrical connection () to a DC/DC converter () that electrically connects the anode () and the cathode () to an energy system (), wherein in a shut-down phase of the fuel cell system (), residual energy present in the fuel cell () can be discharged. According to the invention, the anode () is connected to the energy system () and/or the cathode () via at least one second electrical connection (), wherein the second electrical connection () is a bypass connection to the DC/DC converter () and/or the second electrical connection () is a bypass connection parallel to the fuel cell (), wherein at least the residual energy can be discharged via the second electrical connection (), and the second electrical connection () comprises a resistor ().
