    摘要: 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.

    摘要: A multiphase DC/DC converter has multiple converter cells that are arranged in parallel to one another and clocked in a time-staggered manner. Equipped on the input side and/or output side of the converter cells is a voltage sensor or a current sensor. The latter is connected via an analog-digital converter to a separator, which is provided for separating the output signal of the analog-digital converter into voltage or current values associated with the individual phases of the converter. The separator is connected to a control system, which on the output side provides control signals influencing the clock signals of the converter cells.
