摘要： PROBLEM TO BE SOLVED: To timely output required power when starting feeding in a fuel cell system.
SOLUTION: In the fuel cell system FC, a compressor 41 and a low-pressure valve 24 are temporarily driven for supplying air and hydrogen to a fuel cell stack even in an intermittent operation mode. When the air is supplied, voltage drop in the stop of the system can be suppressed by keeping a fixed amount of air remaining in an air supply system. When hydrogen is supplied, hydrogen permeated to the air supply system is replenished, and the supply delay of hydrogen can be suppressed. Additionally, a signal is inputted from a brake sensor 102, a shift selector 104, or the like and the air and hydrogen are supplied in advance by estimating that a vehicle mounting the fuel cell system FC is accelerated. With such a configuration, delay in power generation occurring when activating and reactivating the fuel cell system FC can be canceled.

摘要： PROBLEM TO BE SOLVED: To provide a control device for a fuel cell powered vehicle, wherein if an anomaly is detected in a fuel cell system, the anomaly can be announced to the surrounding of the vehicle without special operation on the part of by a driver.
SOLUTION: The control device (4) for the fuel cell powered vehicle comprises anomaly-detecting means (S1 to S12) that detect anomalies in the fuel cell system; and an anomaly-announcing means (S13) that, if the anomaly detecting means detect an anomaly in the fuel cell system during driving, announces it to the surrounding of a relevant vehicle through a hazard indicator or the like. The Detection of the anomaly is carried out based on a driver's acceleration request and an actual vehicle speed. Thus, the anomaly in the fuel cell that is extremely likely to lead to a sudden change in vehicle speed can be detected at an early stage.

摘要： PROBLEM TO BE SOLVED: To improve the measuring accuracy of a current detector of a fuel cell in a fuel cell system. SOLUTION: A control unit 60 sets an output terminal voltage of a fuel cell 21 to an OCV (400 V) via a DC/DC convertor 31, when a fuel cell system 20 is not activated, when a vehicle 10 is in a regenerative operation, when the fuel cell 21 is in an intermittent operation, and when the operation of the system 20 is completed. As the result, a current value flowing in a power supplying line 411 can be surely set at 0 A even if the fuel cell 21 stops its operation state. The unit 60 obtains a current value Ad from a fuel cell current sensor 413 and decides an offset correction value Ac for cancellation (0 point correction) of a drift amount.

摘要： PROBLEM TO BE SOLVED: To provide an objective fluid from being mixed with other fluid such as air or the like in connecting a passage and to efficiently utilize the objective fluid. SOLUTION: In connecting a first connecting part 22 connected to a hydrogen storage alloy tank 10 and a second connecting part 32 connected to a hydrogen filling device 12, a primary valve 24 and a secondary valve 36 are opened, and an exhaust valve 42 of an exhaust pipe 40 connected to a space between a secondary valve 26 and the secondary valve 36 is opened. Then the secondary valve 36 is opened by a predetermined opening to discharge the mixture gas in the space to a hydrogen fractionating device 50. After the mixture gas is completely exhausted, the exhaust valve 42 is closed, and the secondary valve 26 and the secondary valve 36 are opened to complete the connection. As the air included in connection is completely exhausted, hydrogen of high purity can be packed in the hydrogen storage alloy tank 10. The hydrogen fractionated by the hydrogen fractionating device 50 is returned to a cylinder bundle 14 of the hydrogen filling device 12.

摘要： PROBLEM TO BE SOLVED: To provide a controlling technology of a humidifying state of a fuel cell having a more superior response property than before. SOLUTION: An electric switch 54 is installed between the fuel cell 130 and a load 160. When the humidifying state of the fuel cell 130 is insufficient, the fuel cell 130 is set in an open-circuit state by opening the electric switch 54, and the humidifying state is improved. Otherwise, in an operation of the fuel cell 130, by opening the electric switch 54 by a prescribed time interval, the fuel cell 130 may be set in the open-circuit state.
