    Abstract: A moisture exchange module has a bundle of moisture-permeable hollow fiber membranes and at least one line element for supplying a gas stream that flows through the hollow fibers in an inner flow. The at least one line element opens out into an inflow region, which is of at least approximately the same cross section as the bundle of hollow fiber membranes. According to the present invention, the at least one line element opens out into the inflow region at an angle of from 60° to 120° with respect to the longitudinal axis of the bundle of hollow fiber membranes without the longitudinal axes of the one line element and of the bundle of hollow fiber membranes intersecting one another. An annular diverter means for diverting the gas flow are provided between the cross section of the line elements through which gas can flow and the inflow region. The diverter means are arranged in such a way that an annular gap is formed, which annular gap is connected to the at least one line element and, on its side remote from the bundle of hollow fiber membranes, is connected to the inflow region.

    Abstract: In a method for regulating a boost pressure of an engine which has a compressor, an actual boost pressure and a setpoint boost pressure are used as input parameters. The setpoint boost pressure is regulated in such a way that a pressure ratio in the compressor does not exceed a limit pressure ratio. A reference boost pressure is ascertained based on a speed of the engine and a load of the engine. A flow and/or a pressure of air supplied to the engine is/are detected and an associated flow signal and/or pressure signal is generated. The smaller of the reference boost pressure and a limit boost pressure is used as a setpoint boost pressure. The limit boost pressure is ascertained based on a limit boost pressure ratio and a speed of the compressor.

    Abstract: The subject of the present invention relates to a method and a protector for reducing degradation of fuel cell systems at transitions in operation, in particular at electrodes or catalysts in a combustion chamber of a stack of a PEM fuel cell system in startup and shutoff events of the fuel cell system. A switchable material delivery device is provided for varying a delivery of material to the fuel cell system, so that a transition from a first state of the fuel cell system to a second state of the fuel cell system can be initiated, such that a potential difference between different electrodes can be effected. At least one reducing mechanism is provided for reducing the potential difference between the different electrodes during the transition, in which the reducing mechanism includes at least one compensating device for an unequal gas distribution by reducing the proportions causing degradation, to reduce degradation. The compensation device includes at least one short-circuiting unit, with which the different electrodes can be short-circuited, in order to reduce the potential difference.

    Abstract: The invention relates to a fuel cell system with at least one fuel cell for electrochemical conversion of two reactants. The fuel cell has two electrode areas, having a first supply line for supplying a first reactant to a first electrode area, and an outlet line, for emission of residual gas from the first electrode area. The residual gas has an electrochemically unconsumed portion of the first reactant, a recirculation element, for feeding the residual gas from the outlet line into the first supply line, and an outlet valve in order to emit the residual gas into an area surrounding the fuel cell system. The invention provides for the fuel cell system to have a monitoring unit in order to control the outlet valve. In particular, the monitoring unit opens the outlet valve when the energy required to feed the residual gas by the recirculation element exceeds an energy potential of the first reactant which is present in the residual gas.
