摘要:
A method includes controlling multiple networked input-parallel/output-parallel inverters of a fuel cell system as a single inverter assembly by a master controller. A fuel cell system includes a plurality of fuel cell segments, a plurality of DC/DC converters and at least one DC/AC inverter, where an output of each of the plurality of the fuel cell segments is connected to a pair of DC/DC converters, and each of the pair DC/DC converters is connected to an opposite polarity bus being provided to the inverter.
摘要:
An electricity converter (7) for controlling an output of the fuel cell (1), a battery (3) for storing electricity of the fuel cell (1), and a load device (5) that operates by electricity of at least one of the fuel cell (1) or the battery (3) are included. Further provided is a controller (25) that calculates current chargeable electricity of the battery (3), load device electricity currently consumed by the load device (5) and current generable electricity of the fuel cell (1), and decreases the output of the fuel cell (1) by the electricity converter (7) when the generable electricity is equal-to or more-than a combined value of the chargeable electricity and the load device electricity.

摘要:
An electrical power supply system has a fuel cell module and a battery. The fuel cell can be selectively connected to the battery system through a diode. The system preferably also has a current sensor and a controller adapted to close a contactor in a by-pass circuit around the diode after sensing a current flowing from the fuel cell through the diode. The system may also have a resistor and a contactor in another by-pass circuit around the diode. In a start-up method, a first contactor is closed to connect the fuel cell in parallel with the battery through the diode and one or more reactant pumps for the fuel cell are turned on. A current sensor is monitored for a signal indicating current flow through the diode. After a current is indicated, a by-pass circuit is provided around the diode.
