20090305108 | Fuel Cell Device - A surface on the fuel electrode side of a lower portion of a separator in a fuel cell stack is made to have water repellency, so that water accumulated in a fuel gas flow path can be appropriately discharged, and thus so that reduction in fuel cell performance and deterioration of the fuel electrode can be surely prevented. For that purpose, in a fuel cell device, a fuel cell having an electrolyte layer interposed between the fuel electrode and an oxygen electrode includes a cell module laminated so as to interpose a separator formed with the fuel gas flow path along the fuel electrode, and a fuel gas flows substantially perpendicularly to the direction of gravity in the fuel gas flow path. The separator is provided with a water-repellent surface on the fuel electrode side of a lower portion thereof. | 12-10-2009 |
20090305109 | Fuel Cell Device - A portion of a fuel electrode corresponding to a portion in a fuel gas flow path where water accumulates is made to contain no catalyst, thus preventing abnormal reaction from occurring, and consequently enabling sure prevention of degradation of the fuel electrode and reduction in fuel cell performance. For that purpose, in a fuel cell device, a fuel cell having an electrolyte layer interposed between the fuel electrode and an oxygen electrode includes a cell module laminated so as to interpose a separator formed with the fuel gas flow path along the fuel electrode, and a fuel gas flows substantially perpendicularly to the direction of gravity in the fuel gas flow path. The fuel electrode includes a catalyst-absent portion which contains no catalyst, provided in a portion corresponding to a water-accumulating portion in which water is accumulated, in the fuel gas flow path. | 12-10-2009 |

20100239929 | FUEL CELL SYSTEM - A fuel cell system has a fuel cell stack generating electricity with a reactive gas supplied thereto and a controller supplying to the fuel cell stack the reactive gas whose pressure is higher than a normal operational pressure on condition that a temperature of the fuel cell stack is equal to or less than a predetermined threshold temperature and that a moisture content of the fuel cell stack is equal to or less than a predetermined threshold value. Where a supply pressure of the reactive gas is raised, an amount of moisture taken away by the reactive gas becomes less, and thus, water balance within the fuel cell stack shifts toward accumulation of moisture contained in the reactive gas into the film-electrode joined body. However, since the moisture content of the fuel cell stack is equal to or less than the predetermined threshold value, the system can improve the starting performance of the fuel cell stack at low temperature while suppressing flooding. | 09-23-2010 |
20110027679 | FUEL CELL SYSTEM - A fuel cell system has a fuel cell stack and a controller. The fuel cell stack is formed by stacking cells. The controller executes first cell voltage recovery processing when the cell voltage of a first cell group, placed at each end of the fuel cell stack, is below a first lower limit voltage threshold and executes second cell voltage recovery processing, which is different from the first cell voltage recovery processing, when the cell voltage of a second cell group, placed at substantially the center of the fuel cell stack, is below a second lower limit voltage threshold. | 02-03-2011 |

20080261089 | Fuel cell system and method for controlling fuel cell system - In a fuel cell unit that generates electric power using fuel gas supplied via an anode gas passage and air supplied via a cathode gas passage, an anode-off gas passage is connected to the downstream side of the anode gas passage. An orifice is provided at the anode-off gas passage and anode-off gas is discharged to the downstream side via the orifice. | 10-23-2008 |
20090075135 | Fuel cell system - The fuel cell system includes a storage portion, a fuel cell, a fuel supply portion, a hydrogen circulation system and a boil-off gas supply portion. The storage portion stores liquid hydrogen. The fuel cell uses hydrogen gas as fuel gas. The fuel supply portion provides hydrogen gas to an anode of the fuel cell. The hydrogen gas is generated caused by a vaporization of liquid hydrogen stored in the storage portion. The hydrogen circulation system includes the anode of the fuel cell. The boil-off gas supply portion provides boil-off gas generated in the storage portion to the hydrogen circulation system. | 03-19-2009 |

20120021309 | FUEL CELL SYSTEM - A fuel cell system capable of inhibiting dew condensation in an area affected by freezing by providing an area for actively promoting dew condensation is provided. The fuel cell system includes a fuel cell and an off-gas passage for allowing an off-gas discharged from the fuel cell flow through, wherein a dew condensation promoting area for promoting dew condensation is placed around a freezing-affected area that will be adversely affected by freezing. | 01-26-2012 |

20090208786 | FUEL CELL SYSTEM - There is provided a fuel cell system capable of notifying a user that control for low-temperature countermeasure is performed, without any strange feeling and false recognition. When control for low-temperature countermeasure such as scavenging at system termination or warm-up at system start-up is made, the user is reliably notified that the control is performed, by a text message or a speech message. Consequently, even in a situation where the system is operating after an ignition key is turned off, the user suffers neither strange feeling nor false recognition. | 08-20-2009 |

20100151360 | ONBOARD FUEL CELL SYSTEM AND METHOD OF DISCHARGING HYDROGEN-OFF GAS - Consumed hydrogen-off gas is discharged from a fuel cell via a hydrogen-off gas exhaust flow passage. Consumed oxygen-off gas is discharged from the fuel cell via an oxygen-off gas exhaust flow passage. The oxygen-off gas flowing through the oxygen-off gas exhaust flow passage and the hydrogen-off gas flowing through the hydrogen-off gas exhaust flow passage are mixed and diluted in a mixing portion. The gases mixed in the mixing portion flow into a combustor via a gas-liquid separator. The combustor, which includes a platinum catalyst, causes hydrogen contained in the mixed gases to react with oxygen by combustion and further reduces the concentration of hydrogen contained in the mixed gases. The mixed gases whose concentration of hydrogen has been reduced by the combustor is discharged to the atmosphere. | 06-17-2010 |
