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： The invention relates to a method for optimizing the efficiency of an energy system, which system has at least one energy unit that is coupled to a control unit and a DC/DC converter for regulating the power output of the energy unit, and the control unit regulates the power output to an electrical component via the DC/DC converter as a function of an operating state of the energy system. According to the invention, it is provided that the energy unit communicates with an observer via a first information channel, and information from the energy unit is transmitted during the operation of the energy system via the first information channel to the observer, which from the transmitted information ascertains the efficiency performance of the energy unit and transmits the efficiency performance to the control unit via a second information channel, as a result of which the overall efficiency of the energy system is improved.
