摘要： An externally-controllable electrical power generating system for providing auxiliary or backup power to a load bus or device. The system may be used indoors, and generally includes a power source comprising a first DC output, an electrical storage unit comprising a DC input coupled to the first DC output of the power source, the electrical storage unit further comprising a second DC output. An inverter coupled to the second DC output receives power, the inverter having a first AC output that can be synchronized with an AC load bus or AC grid. The system includes a contactor connected between the first AC output and an AC load bus, and is controllable with an external controller operated by a utility or a managing entity, such that the external controller can enable the controller to connect or disconnect the contactor.

摘要： Disclosed is a method of controlling an air supply system for a fuel cell. The air supply system includes a fuel cell stack, an air channel to supply air to an inlet of the fuel cell stack, a gas adsorption unit disposed on the air channel and configured to adsorb oxygen contained in air introduced into the air channel. In particular, the method includes: determining whether a power generation operation of the fuel cell stack is resumed; when the power generation operation of the fuel cell stack is resumed, controlling a voltage source to apply a voltage to the gas adsorption unit; and supplying air to the fuel cell stack through the air channel in a state in which the voltage is applied to the gas adsorption unit.

摘要： Even in a case where a rapid variance is demanded as to the input voltage of a converter and the output terminal voltage of a fuel cell, stable converter control is realized. On judging that the change ratio of the demand power of a fuel cell exceeds a set threshold value, a controller executes converter stabilization processing. First, the controller controls a battery converter so that an input voltage of an inverter becomes a set target input voltage. Then, after the input voltage of the inverter reaches the target input voltage, the controller controls an FC converter so that an output terminal voltage of the fuel cell becomes a set target output terminal voltage.
