摘要： PROBLEM TO BE SOLVED: To provide a method of dismissing residual hydrogen from a fuel cell stack after stoppage of a fuel cell. SOLUTION: Nitrogen flow is temporarily provided by providing air flow and removing oxygen from the air flow with the use of an absorbent bed, then the nitrogen flow is made to pass to a fuel cell stack. After the fuel cell stack 34 is stopped, an absorber inlet valve 20 and an absorber outlet valve 24 are opened and a hydrogen flow valve 15 is closed, air flow 12a is displaced to an absorber 16, and then, by passing the obtained nitrogen flow 44 to an anode side 40 of the fuel cell stack 34, residual hydrogen can be dismissed from the fuel cell stack 34. An absorbent material 17 in the absorber 16 can be regenerated during an operation of the fuel cell stack 34 continued. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide the most suitable procedure for braking processing at failure time in a permanent motor drive unit. SOLUTION: An apparatus comprises a multi-phase inverter, a failure detector for indicating the detection of failure, a sensor offering a speed signal indicating the PM (performance monitor) motor whether its speed is larger than a transition speed, and a controller. The controller can be operated, in such a manner that an open-circuit response or a short-circuit response are applied to the multi-phase inverter. The open-circuit response is applied, when the failure is detected and further when the PM motor speed is larger than the transition speed. The short circuit response is applied, when the failure is detected and further when the PM motor speed is smaller than the transition speed. The transition speed is a fixed prescribed speed or a regulated prescribed speed. COPYRIGHT: (C)2008,JPO&INPIT

Each rectification control switch is coupled with the corresponding winding of stator winding so that a corresponding stator winding circuit may be formed between the neutral terminal and each node. Each rectification control switch is equipped with a first diode connected in parallel with a series switch circuit. Each series switch circuit is equipped with a second diode and a switch element connected in series to the second diode. The controller is coupled with the switch element and the primary rectifying switch pair so as to control the ON time and the OFF time of the primary rectifying switch to the point of time when the supply voltage becomes equal to the counterelectromotive force.

摘要： PROBLEM TO BE SOLVED: To provide an integrated technique for hydrating a fuel cell which can avoid high cost, excessive complexity or poor operability associated with traditional techniques. SOLUTION: This integrated technique for hydrating a fuel cell includes a device and method which extracts water from a moisture-rich fuel cell flowpath and supplies the water to other components of a fuel cell system that require water, and a water transport unit is integrated into the fuel cell so that the size, weight and complexity of the fuel cell is minimized. In an embodiment, the device includes many flowpaths that include an active region and inactive regions. The water transport unit includes a moisture-donating fluid channel and a moisture-accepting fluid channel, where the latter is fluidly connected with a portion of the fuel cell that is in need of humidification. Upon passage of a moisture-donating fluid through the inactive region of the device flowpath, at least some of the water contained therein passes through the water transport unit to a portion of the fuel cell that is in need of humidification.
