摘要： A control apparatus controls an electric power supply apparatus configured to supply electric power to a working machine. The electric power supply apparatus is provided with a fuel cell. The control apparatus is provided with a restriction request acquisition unit configured to acquire a restriction request for requesting restriction of the supply of the electric power via a communication network, and a restriction unit configured to restrict the supply of the electric power in a case where the restriction request acquisition unit acquires the restriction request. The control apparatus may be provided with an end detection unit configured to detect end of use of the working machine. The restriction unit may decide to start the restriction in a case where, after the restriction request acquisition unit acquires the restriction request, the end detection unit detects the end of the use of the working machine.

摘要： A controller for a fuel cell system controls generated power of a fuel cell stack by switching a generation state of the fuel cell stack based on a state of charge of a power storage device. The generation state includes a first generation state, in which the fuel cell stack is caused to generate a first generated power, a second generation state, in which the fuel cell stack is caused to generate a second generated power greater than the first generated power, and a third generation state, in which the fuel cell stack is caused to generate a third generated power greater than the second generated power. The controller calculates a power reference value indicating an actual result of power generation of the fuel cell stack from the detected generated power of the fuel cell stack, and updates the second generated power based on the power reference value.

摘要： Flow battery systems and control methods are disclosed. The flow battery includes components such as positive electrolyte tank, a negative electrolyte tank, a primary stack having a positive porous electrode and a negative porous electrode separated by a membrane, a power bus linked to the electrodes, an electrolyte pump and an auxiliary stack, etc. The power load on a power bus is monitored and as required pumps are activated if the detected power load on the power bus is greater than a first threshold power load. One of the pumps are deactivated if the detected power load on the power bus is less than a second threshold power load which is lower than the first threshold power load.

摘要： A hydrogen-producing device is provided which can start up without receiving an energy supply from the outside. This hydrogen-producing device 1 is provided with an input unit 11 which is connected to a hydrogen source 41, a reformer 12 which produces a hydrogen-containing gas, a hydrogen storage container 13, a fuel battery 15 which generates power using the hydrogen-containing gas, and a control unit 18. The hydrogen storage container 13 is connected to a fuel hydrogen supply path 16 for supplying hydrogen to the fuel battery 15, and to an external supply path 17 which supplies hydrogen to an external load 42. The control unit 18 stores a threshold value of the hydrogen-containing gas necessary for start-up of the fuel battery 15, and controls the amount stored in the hydrogen storage container 13 to be greater than or equal to the amount necessary for start-up of the fuel battery 15. Further, when starting up the hydrogen-producing device, the fuel battery 15 generates power by receiving a supply of the hydrogen-containing gas stored in the hydrogen storage container 13 and supplies power to the reformer 12 from a power supply path 30. The reformer 12 starts up and hydrogen is produced.

摘要： A method for operating a fuel cell system includes drawing a base level DC electric energy from a first fuel cell of a first type to a combined DC bus, measuring a DC voltage at the combined DC bus, determining whether the DC voltage at the combined DC bus falls short of a DC voltage threshold, and drawing a variable DC electric energy from a second fuel cell of a second type different from the first type in response to determining that the DC voltage at the combined DC bus falls short of the DC voltage threshold.

摘要： A control method for fuel cell system capable of executing an idle stop operation is provided, in which operation power generation of a fuel cell is selectively stopped according to a required output of a load and cathode gas is intermittently supplied to the fuel cell during an operation stop. An upper limit value and a lower limit value of an output voltage of the fuel cell during the idle stop operation is set, the cathode gas is intermittently supplied with the output voltage of the fuel cell set at a value between the upper limit value and the lower limit value, a wet/dry state of the fuel cell is detected, a wet/dry appropriate range in which the wet/dry state of the fuel cell during the idle stop operation is appropriate is set, and it is determined whether or not the detected wet/dry state of the fuel cell is within the set wet/dry appropriate range. If the wet/dry state of the fuel cell is determined to be outside the set wet/dry appropriate range, the output voltage of the fuel cell is reset, and the cathode gas is intermittently supplied with the output voltage of the fuel cell set at a value between the upper limit value and lower limit value of the reset output voltage.

摘要： A method and system for controlling a fuel cell vehicle are provided. The method includes determining, by a controller, a driving pattern of a driver based on driving information including acceleration and deceleration information. A condition for activation of an idling-stop of a fuel cell is then set based on the determined driving pattern and the fuel cell is stopped from generating electric energy when the condition for activation of the idling-stop is satisfied.
