20100026092 | POWER SOURCE SYSTEM, POWER SUPPLY CONTROL METHOD OF POWER SOURCE SYSTEM, POWER SUPPLY CONTROL PROGRAM OF POWER SOURCE SYSTEM, AND COMPUTER READABLE RECORDING MEDIUM HAVING POWER SUPPLY CONTROL PROGRAM OF POWER SOURCE SYSTEM RECORDED THEREON - A power source system capable of temporarily increasing the power supply capacity of a power accumulator when an interruptible power source is stopped. Upon receiving stop information of the interruptible power source from an integrated control ECU, a controller reduces an operable voltage that is determined as an output voltage for ending discharge of the power accumulator, outputs the reduced operable voltage from a communication part to the integrated control ECU. The integrated control ECU controls a charge/discharge control device based on the reduced operable voltage, and increases the power supply capacity of the power accumulator. | 02-04-2010 |
20100026244 | POWER SOURCE SYSTEM, POWER SUPPLY CONTROL METHOD FOR THE POWER SOURCE SYSTEM, POWER SUPPLY CONTROL PROGRAM FOR THE POWER SOURCE SYSTEM, AND COMPUTER-READABLE RECORDING MEDIUM WITH THE POWER SUPPLY CONTROL PROGRAM RECORDED THEREON - The present invention provides a power source system that increases the power supply capacity of a power source device and continuously supplies the power necessary for a load device when a power source device stops. A control unit has a state quantity setting unit that sets a first target state quantity indicating a state of charge of the power storage device that is to be a target value when charge and discharge of the power storage device are controlled. When the power source device stops, the state quantity setting unit can change the first target state quantity to a second target state quantity that is to be a target value exceeding the first target state quantity and can increase the target state quantity of the power storage device. As a result, when the power source device stops, charge and discharge of the power storage device are controlled on the basis of the target state quantity exceeding that during the operation of the power source device. Therefore, the state of charge of the power storage device can be improved over that during the operation of the power source device. As a result, the power supply capacity of the power source device can be increased and the power necessary for the load device can be continuously supplied, in place of the power source device. | 02-04-2010 |

20110143233 | FUEL CELL SYSTEM AND CONTROL METHOD THEREFOR - A fuel cell system for optimally controlling an amount and temperature of liquid component stored in a gas-liquid separator, and its control method. The fuel cell system includes a fuel cell, a pump for supplying gas to the fuel cell, a gas-liquid separator for storing a liquid component discharged at least from a cathode side of the fuel cell, a cooler for cooling the stored liquid component, a temperature detector for measuring temperature of liquid component, a liquid level detector for measuring an amount of liquid component, and a controller for controlling a flow rate of gas from the pump and heat discharge by the cooler. The controller controls at least heat discharge by the cooler or a flow rate of gas supplied from the pump based on an output of the temperature detector and an output of the liquid level detector. | 06-16-2011 |
20110165487 | METHOD FOR CONTROLLING THE FLOW RATE OF FUEL SUPPLIED TO A FUEL CELL, FUEL SUPPLY DEVICE, AND FUEL CELL SYSTEM USING THE SAME - In a method for controlling a flow rate of fuel supplied to a fuel cell, a voltage change is examined while the flow rate of the fuel is increased step by step in a state in which a constant current is output. Conversely, when the voltage change becomes small, the flow rate of fuel is reduced step by step. When the voltage change becomes large, the flow rate of the fuel in the previous step is employed. Thus, the flow rate of fuel can be optimized in accordance with an operating state of the fuel cell. | 07-07-2011 |
20110177418 | FUEL CELL STACK AND FUEL CELL SYSTEM USING THE SAME - A fuel cell stack formed by laminating thin end plates, separators, and the like, includes a first side surface and a second side surface parallel to the laminating direction. An anode side end plate has a plane portion on a first side surface. The dimension in the laminating direction of the plane portion is larger than a thickness of one of the end plates in a portion where the end plates sandwich a membrane electrode assembly. The plane portion is provided with a fuel inlet port for taking in fuel from the outside. | 07-21-2011 |

20120129057 | FUEL CELL SYSTEM - A fuel cell system has a separation unit for separating gas-liquid mixed fluid discharged from the fuel cell stack. The separation unit has a tank for storing the separated liquid. A pair of metal electrodes is disposed on the side surfaces of the tank opposed to each other. The electrodes are used to measure the amount of the liquid in the tank and also promote the heat dissipation of the liquid in the tank. This can suppress the transpiration of the liquid in the tank and cool the liquid to a temperature suitable for the reuse in the fuel cell stack. | 05-24-2012 |
