20100176220 | MOVING BODY - A moving body, such as a vehicle, having one or more fuel cells mounted thereon. The fuel cells, which power the moving body, generate electricity and release water as a by-product. Accordingly, the moving body includes a water discharge module that releases water produced by the fuel cells to the atmosphere using a water outlet. The water outlet may be located in a front section of the moving body. The moving body may further include a water tank that temporarily stores water before releasing the water to the atmosphere. | 07-15-2010 |
20110313605 | MOVING BODY - Water contained in exhaust gas discharged from a fuel cell stack is separated by a gas-liquid separator and is accumulated in a recovery tank. The procedure of the invention sets a release amount of water and selects one or multiple positions for water release, based on the driving conditions including the vehicle speed and the acceleration, the turning state, activation or non-activation of skid reduction control, the distance from any object detected by clearance sonars, a distance from a subsequent vehicle measured by an extremely high frequency radar, and the presence of raindrops detected by a raindrop detection sensor, and releases the water accumulated in the recovery tank from water outlets at the selected one or multiple positions among water outlets at multiple different locations. This arrangement ensures adequate release of the water produced by the fuel cell stack to the atmosphere. | 12-22-2011 |

20080220303 | Fuel Cell System - A fuel cell system that generates electricity using an electrochemical reaction of fuel gas and oxidizing gas, having: a pressure adjustment valve which is provided on a fuel gas supply path for conducting the fuel gas from a fuel gas supply source to a fuel cell and which adjusts the supply gas pressure of the fuel gas; a degree of opening adjustment valve provided downstream of the pressure adjustment valve on the fuel gas supply path, the degree of opening thereof being set in stages or continuously in accordance with a degree of opening signal; and control means that adjusts the degree of opening adjustment signal in accordance with the operating condition of the fuel cell system and controls the state quantity of fuel gas supplied to the fuel cell to a target quantity. In this way, the pressure of fuel gas (for example, hydrogen gas) whose pressure has been reduced by the pressure adjustment valve can be further adjusted to the target pressure by the degree of opening adjustment valve provided downstream of the pressure adjustment valve in accordance with the operating condition of the fuel cell system. | 09-11-2008 |
20090239105 | Fuel Battery System, Method for Detecting Gas Leakage in Such System, and Mobile Object - The accuracy of detecting gas leakage in a fuel battery system is improved. A fuel battery system includes a fuel battery to which a reactive gas is supplied to generate power, and a gas passage (a fuel gas supply path and a fuel gas circulation path) connected to this fuel battery, this gas passage is provided with a plurality of adjoining closed spaces, and the system includes a detecting unit (a control section) to detect gas leakage in one closed space in a state in which at least a pressure of another closed space adjoining the one closed space as a gas leakage detection target on a downstream side is lowered. | 09-24-2009 |
20090286110 | Fuel Cell System and Its Operation Stop Method - The present invention relates to a fuel cell system including a fuel cell which has a catalyst layer therein and which receives supply of a reactive gas to generate a power, and a refrigerant system which supplies a refrigerant to the fuel cell to control a temperature of the fuel cell, and it also relates to a method for stopping an operation of the system. When the system is operated in a low-temperature environment, the system cannot be restarted owing to freezing in the fuel cell. Therefore, during stop of the system, control has heretofore been performed so that a flow rate of a coolant to the fuel cell is reduced to lower a cooling performance and that the operation of the fuel cell is continued to raise the temperature of the fuel cell or the like. However, the control is performed regardless of a situation during the next system start, so that there has been a problem that the control might become useless. According to the present invention, in the above system, in a case where it is presumed that the temperature of the fuel cell during the next system start is a predetermined temperature or less, the supply of the refrigerant is stopped during the system stop, and the supply of the refrigerant is resumed after elapse of a predetermined time, whereby the above problem is solved. | 11-19-2009 |
