20130004870 | FUEL CELL SYSTEM AND METHOD FOR CONTROLLING ELECTRIC CURRENT OF SAME - In a fuel cell system, when an electric current drawn from fuel cells is controlled based on a target power generation value, an upper limit of the electric current is optimally set to make suspensions of operation caused by voltage drops to be as infrequent as possible. The upper limit of the electric current is set by adding a predetermined offset value (e.g., 2 A) to an average value of the electric current before a predetermined delay time (e.g., 10 seconds). Moreover, when the electric current drawn from the fuel cells is controlled based on a target power generation value, the value of the electric current is compared with the upper limit of the electric current, to control the electric current. | 01-03-2013 |

20140308596 | METHOD AND DEVICE FOR STOPPING SOLID-OXIDE FUEL CELL SYSTEM - A SOFC system houses a reformer and a fuel cell stack in a module case. Each cell forming the fuel cell stack is made of a porous material having a composition containing at least nickel metal, includes a cell support having a gas passage through which the fuel gas from the reformer flows from an lower end to an upper end on the inside thereof, and the excessive fuel gas is combusted at the upper end of the gas passage. Here, after the power generation stops, until the temperature of the upper end of the fuel cell stack falls below the minimum oxidation temperature of the nickel metal, the supply amount of the fuel gas to the fuel cell stack is controlled in terms of a heat flow rate within a range of 0.1 to 0.5 times that during the system rated power generation. | 10-16-2014 |

In the SOFC system, a fuel gas flow rate to a fuel cell stack is set at F1 at the time of start-up. At a time point when a temperature T of the fuel cell stack reaches a first temperature T1 or higher after the temperature is started to increase, when it is determined that the stack temperature T at the time of the previous system stop is lower than or equal to a predetermined value Tb, the fuel gas flow rate is decreased to F2a (which is less than F1), and when it is determined that the stack temperature T is higher than the predetermined value Tb, the fuel gas flow rate is decreased to F2b (which is less than F2a) to slow the temperature increase rate. Furthermore, when the stack temperature T reaches T2, the fuel gas flow rate is returned to F1 so as to increase the fuel gas flow rate and then the process proceeds to the next process. | 10-23-2014 |

20130316256 | FUEL CELL SYSTEM - This fuel cell system monitors the temperature of an off-gas combusting unit detected by a combustor temperature detecting unit in a constant output operation state such as a rated operation state where a sweeping current of a cell stack becomes constant, rather than directly measuring the fuel property, and controls the flow rate of the cathode gas so that the temperature of the off-gas combusting unit reaches a target temperature. Moreover, the fuel cell system determines the fuel property based on the variation of the flow rate of the cathode gas changed until the temperature of the off-gas combusting unit reaches the target temperature and the temperature of the cathode gas. Thus, it is possible to simplify the configuration required for determining whether the fuel property has changed or not as compared to a conventional method of measuring a plurality of factors of the fuel property. | 11-28-2013 |
