Publication number: 20110159390Abstract: Deterioration at the start-up and deterioration during the leaving period are suppressed in a good balance. As a system shutdown process, a controller (30) causes consumption of the air (oxygen) present in an oxidant electrode of a fuel cell stack (1) (oxygen consumption control). Further, after the termination of the oxygen consumption control, the controller (30) performs control to set a medium pressure hydrogen valve (13) and a hydrogen pressure adjustment valve (14) in a closed state. The controller (30) thereby causes hydrogen to be held in a passage located between the medium pressure hydrogen valve (13) and the hydrogen pressure adjustment valve (14). During a system shutdown period, a predetermined amount of hydrogen (medium pressure hydrogen) held in the hydrogen supply passage (L1) at a position between the medium pressure hydrogen valve (13) and the hydrogen pressure adjustment valve (14) can be supplied to the fuel electrode of the fuel cell stack (1) through a bypass passage (L2).Type: ApplicationFiled: June 15, 2009Publication date: June 30, 2011Inventors: Mitsunori Kumada, Ryoichi Shimoi, Hayato Chikugo, Takashi Aoyama

Patent number: 7928376Abstract: There is provided an element mapping unit, scanning transmission electron microscope, and element mapping method that enable to acquire an element mapping image very easily. On the scanning transmission electron microscope, the electron beam transmitted through an object to be analyzed enters into the element mapping unit. The electron beam is analyzed of its energy into spectrum by an electron spectrometer and an electron energy loss spectrum is acquired. Because the acceleration voltage data for each element and window data for 2-window method, 3-window method or contrast tuning method are already stored in a database and accordingly the spectrum measurement is carried out immediately even when an element to be analyzed is changed to another, the operator can confirm a two-dimensional element distribution map immediately.Type: GrantFiled: September 23, 2005Date of Patent: April 19, 2011Assignee: Hitachi, Ltd.Inventors: Kazutoshi Kaji, Kazuhiro Ueda, Koji Kimoto, Takashi Aoyama, Shunroku Taya, Shigeto Isakozawa

Publication number: 20110076580Abstract: For implementing a stop control which extracts a current from a fuel cell and consumes a cathode side oxygen at a system stop, the current extraction from the fuel cell is ended in a state that a certain quantity of oxygen smaller than when the current extraction is started remains on a cathode side of the fuel cell. With this, the hydrogen movement to the cathode side after the system stop can be effectively suppressed and thereby a cathode internal hydrogen concentration at the system start can be kept low, thus making it possible to properly process the cathode side hydrogen at the system start.Type: ApplicationFiled: June 4, 2009Publication date: March 31, 2011Applicant: NISSAN MOTOR CO., LTD.Inventors: Ryoichi Shimoi, Hayato Chikugo, Mitsunori Kumada, Takashi Aoyama
