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: A moisture exchange module includes a bundle of moisture-permeable hollow fiber membranes through which a first gas stream can flow. The bundle of hollow fiber membranes is arranged in a housing, the housing being provided with line elements for supplying and discharging a second gas stream, which flows around the hollow fiber membranes. Between the bundle of hollow fiber membranes and the housing there is at least one flow space, which extends over at least approximately the entire length of that region of the bundle of hollow fiber membranes through which the first gas stream can flow. The at least one flow space surrounds only a small part of the circumference of the bundle of hollow fiber membranes, so that ultimately a moisture exchange operated in cross-current mode is formed. This can preferably be used for the humidification of feed air for fuel cell systems.

Abstract: A device used for humidifying the flow of a gas which is to be humidified, e.g., fed to a fuel cell system. A moist gas, e.g. a moist waste gas from said fuel cell system is used for said humidification, whereby said gas flows together with the gas flow in a humidifying device. The two gas flows are separated from each other by a membrane in the humidifying device. The membrane is exclusively permeable for water vapour. According to the invention, at least one bypass line is provides. At least one of the gas flows can be partially guided via said bypass line around the region of the membrane in the humidifying device. The saturation point can thus be freely adjusted in an advantageous manner in the gas which is to be humidified.

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.
