摘要:
In a fuel cell system having a gas generation system for providing hydrogen from a carbon- and hydrogen-containing medium for a fuel cell unit, means are provided for adjusting pressure in the gas generation system and/or mass flow through the fuel cell unit, upstream of the fuel cell unit. In a transition from a part-load range to a full-load range, the pressure can be at least briefly reduced, and in a transition from a full-load range to a part-load range, the pressure can be at least briefly increased.

A photovoltaic module including a plurality of single photovoltaic cells is described. The photovoltaic module includes an electric connection device having power connections for outputting generated photovoltaic energy to a consumer network and an electric cutout device having cutout terminals at the power connections of the electric connection device and at least one safety circuit breaker through which the power connections of the electric connection device may be disconnected electrically from the consumer network. The electric cutout device includes a trigger device which is formed with a thermal sensitivity and/or a smoke sensitivity, which is connected to the safety circuit breaker in such a way that upon detection of a temperature and/or of smoke exceeding a predetermined threshold, the safety circuit breaker electrically disconnects the power connections of the electric connection device from the consumer network. A combination of several such photovoltaic modules is also described.
摘要:
A control apparatus for a fuel cell stack having an operation control module is provided. The operation control module is configured in terms of programming and circuitry in order to control a large number of sensor or actuator systems that are relevant to normal operation. The sensor or actuator systems relate to the operating state of the fuel cell stack during normal operation and have a safety control module that is designed in terms of programming and circuitry to control safety-relevant sensor or actuator systems. The safety-relevant sensor or actuator systems relate to the safety functions of the fuel cell stack and the safety control module is in the form of an assembly which operates autonomously with respect to the operation control module. A method for controlling the fuel cell stack and the operation control module is also provided.
