Abstract: In a fuel cell stack, fuel, such as often hydrogen, electrochemically reacts with an oxidant, such as ambient air, and electric energy is generated from chemical energy. During the reaction, a proton exchange membrane (PEM) separates the fuel from the oxidant during the electrochemical process. A supply system for the fuel cell stack comprises an adjustable humidifying device for humidifying a supply gas which is supplied to the fuel cell stack, as a function of a control signal; and a dehumidifying device, which is configured to dehumidify an exhaust gas that is formed from the supply gas conducted through the fuel cell stack, and to discharge the same as a dehumidified exhaust gas. A controller, which generates the control signal, is configured from a programming and/or switching point of view to generate the control signal based on the gas temperature of the dehumidified exhaust gas.

Abstract: A device for controlling the differential pressure between an anode area and a cathode area of a fuel cell has a differential pressure sensor for measuring the differential pressure between the anode area and the cathode area. A first actuator controls the flow of fuel into the anode area, and a control device regulates or controls the first actuator, on the basis of the signal of the differential pressure sensor.

Abstract: A fuel cell system includes a fuel cell with an anode chamber and a cathode chamber. The fuel cell system also includes a recirculation device that recirculates anode exhaust gas to the anode input, which includes a discharge line for discharging liquid and/or gas from the region of the recirculation device, and an air conveying device for supplying the cathode chamber with a supply air flow. A water separator, which is connected to the discharge line and through which at least a portion of the supply air flow passes, is situated between the air conveying device and the cathode chamber in the area of the supply air flow.
