摘要： An electric motor (5) and an accessory circuit (7, 8) are connected in parallel to an output terminal (1A) of a fuel cell power plant (2). A secondary battery (3) is connected to the output terminal (1A) through a DC/DC converter (6) which controls an output voltage in both directions. The accessories (7, 8) are directly driven by the output of the fuel cell power plant (2). A reduction in the output voltage of the fuel cell power plant (2) resulting from an increase in the load of the electric motor (5) is prevented by discharging power from the secondary battery (3) via the DC/DC converter (6). By directly supplying electric current output from the fuel cell plant to the accessory circuit (7, 8) without passing through the DC/DC converter (6), the power loss due to the DC/DC converter (6) is reduced.

摘要： An apparatus includes a fuel cell subsystem, a first circuit and a second circuit. The fuel cell subsystem produces power for a load in response to receiving a flow of a reactant, and the first circuit is coupled to the fuel cell subsystem to halt the flow to the fuel cell stack and isolate the fuel cell stack from the load after the flow is halted. The second circuit monitors a characteristic of the fuel cell subsystem and receives power from the stack to dissipate a portion of the reactant that remains in the stack while the flow is halted.

摘要： Propulsion control system and method are provided for use in vehicles including a propulsion motor that is powered by a fuel cell. The fuel cell unit produces a compatible voltage for the propulsion motor, thereby removing the need for a dc/dc boost converter. A buck/boost converter and a standard 12 volt battery are used to start the fuel cell. An inverter receives dc electric voltage from the fuel cell and outputs ac electric voltage to the propulsion motor. A vehicle controller receives a voltage input from the fuel cell unit and outputs a current reference to a comparing device. The comparing device compares the current reference from the vehicle controller to an actual current of the fuel cell unit and then outputs a signal to a PI control which outputs a control signal to a fuel cell controller, whereby the power output of the fuel cell is controlled based on the actual current of the fuel cell.
