DEVICE AND METHOD FOR STARTING AND OPERATING A FUEL CELL INSTALLATION

摘要

The invention relates to a device and a method for starting and operating a fuel cell installation (2) that can be connected to an alternating current supply system (10). A bi-directional converter (26) is configured in such a way that during normal operation a direct current that is generated by the fuel cell stack (4) of the fuel cell installation (2) is converted into an alternating current that can be supplied to the alternating current supply system (10). Conversely, an alternating current of the fuel cell installation (2) that is made available via the alternating current supply system (10) is converted into a direct current that can be supplied to a direct current link (14). This obviates the need for additional energy sources and additional equipment for the supply of consumers (6) of the fuel cell installation (2), even during a starting operation.
