20100190080 | FUEL CELL SYSTEM AND ITS CONTROL METHOD - Here is disclosed a fuel cell system comprising: a fuel cell; a fuel gas system which supplies a fuel gas to the fuel cell and circulates the gas discharged from the fuel cell; a purge valve which discharges the gas from the fuel gas system; and control means for controlling the opening/closing operation of the purge valve. The control means controls the opening/closing operation of the purge valve so that impurities partial pressure in the fuel gas system is constant in the entire load region. | 07-29-2010 |
20100203411 | FUEL CELL SYSTEM AND MOBILE OBJECT - A fuel cell system of the present invention is provided with a fuel cell, a fuel gas supply system that supplies a fuel gas to the fuel cell, and an oxidant gas supply system that supplies an oxidant gas to the fuel cell, and, when operation end processing is started, a flow rate of the fuel gas supplied to the fuel cell is increased only by a predetermined amount that is determined based on a temperature environment of the fuel cell system. As a result, when the operation of the fuel cell system is ended, the fuel gas at the optimum flow rate in accordance with the temperature environment is provided, thereby efficiently preventing deterioration of the fuel cell after the end of the operation. | 08-12-2010 |
20100285382 | FUEL CELL SYSTEM AND MOBILE ARTICLE - The fuel cell system is provided with a fuel cell, a fuel supply system for supplying fuel gas to the fuel cell, an injector for regulating the gas state upstream in the fuel supply system and supplying the gas downstream, and control means for driving and controlling the injector at a predetermined drive cycle. The control means sets the working state of the injector in response to the operating state of the fuel cell. | 11-11-2010 |
20110212377 | FUEL CELL SYSTEM AND MOBILE ARTICLE - There is disclosed a fuel cell system including a fuel cell, a fuel supply system to supply a fuel gas to the fuel cell, an injector which adjusts a gas state on an upstream side of the fuel supply system to supply the gas to a downstream side, and a control unit which drives and controls the injector in a predetermined drive cycle. The control unit sets the drive cycle of the injector in accordance with an operation state of the fuel cell. | 09-01-2011 |
20120120548 | CAPACITOR ASSEMBLY - A capacitor apparatus includes eight capacitor elements connected in parallel to an alternating-current current source. The impedance of a bus bar between the (j+1)th (j is 1 to 6) capacitor element and the (j+2)th capacitor element from a connecting terminal is (j+1) times the impedance of the bus bar between the first capacitor element and the second capacitor element from the connecting terminal. The impedance of the bus bar between the (j+1)th capacitor element and the (j+2)th capacitor element from a connecting terminal is (j+1) times the impedance of the bus bar between the first capacitor element and the second capacitor element from the connecting terminal. | 05-17-2012 |
20130323615 | FUEL CELL SYSTEM AND MOBILE ARTICLE - There is disclosed a fuel cell system including a fuel cell, a fuel supply system to supply a fuel gas to the fuel cell, an injector which adjusts a gas state on an upstream side of the fuel supply system to supply the gas to a downstream side, and a control unit which drives and controls the injector in a predetermined drive cycle. The control unit sets the drive cycle of the injector in accordance with an operation state of the fuel cell. | 12-05-2013 |
