摘要： There are provided a an anode-side water discharge controller that controls a circulation flow rate of the anode gas pump so as to discharge anode-side liquid water residing in the anode-side flow path, and a cathode-side water discharge controller that controls a supply flow rate of the cathode gas pump so as to discharge cathode-side liquid water residing in the cathode-side flow path. The anode-side water discharge controller and the cathode-side water discharge controller execute water discharge by running a pre-selected one of the anode gas pump and the cathode gas pump, and then running the other of the anode gas pump and the cathode gas pump.

摘要： When a first timing at which a fuel gas is injected to a fuel gas supply flow path by an injector and a second timing at which water residing on a circulation flow path is discharged by controlling rotating speed of a circulation pump coincide with each other, a controller performs either: (i) a first process of operating the circulation pump at a preset RPM without injecting the fuel gas to the fuel gas supply flow path by the injector; or (ii) a second process of injecting the fuel gas to the fuel gas supply flow path by the injector and operating the circulation pump at an RPM lower than the preset RPM.

摘要： Brennstoffzellensystem (10) umfassend: eine Brennstoffzelle (20), die ein Reaktionsgas zur Erzeugung einer Leistung empfängt; eine Reaktionsgasversorgungsvorrichtung (41, 47), die das Reaktionsgasgas der Brennstoffzelle (20) zuführt; eine Aufwärmvorrichtung, die die Brennstoffzelle (20) durch eine Betriebsweise mit im Vergleich zum Normalbetrieb geringem Wirkungsgrad aufheizt; und eine Steuervorrichtung (70), die die Zufuhr des Reaktionsgases zur Brennstoffzelle (20) reduziert, während die Ausgangsspannung der Brennstoffzelle (20) auf einem fixen Wert gehalten wird, wenn ein Leistungserzeugungsbefehlswert für die Brennstoffzelle (20) abnimmt, während die Betriebsweise mit geringem Wirkungsgrad durchgeführt wird und wenn die Zufuhr des Reaktionsgases zur Brennstoffzelle (20) derart gesteuert werden kann, daß sie der Abnahme des Leistungserzeugungsbefehlswerts folgt, wobei die Steuervorrichtung so gestaltet ist, daß sie die Zufuhr des Reaktionsgases zur Brennstoffzelle steuert und die Ausgangsspannung der Brennstoffzelle (20) erhöht, wodurch eine den Leistungserzeugungsbefehlswert übersteigende Überschußleistung (Ws) in eine Kapazitätskomponente (29) der Brennstoffzelle (20) geladen wird, wenn die Zufuhr des Reaktionsgases nicht derart gesteuert werden kann, daß sie der Abnahme des Leistungserzeugungsbefehlswerts folgt.

摘要： A fuel cell system according to the invention is equipped with a drive motor (16), a fuel cell (11) that generates electric power through an electrochemical reaction of oxidizing gas containing oxygen and fuel gas containing hydrogen and sup-plies the drive motor with electric power, normal electric power generation means (20) for performing normal electric power gen-eration under a condition that the fuel cell not be warmed up, warm-up electric power generation means (20) for performing warm-up electric power generation with lower electric power generation efficiency than normal electric power generation to cause a system loss for warming up the fuel cell, and warm-up control means (20) for controlling performance of warm-up electric pow-er generation by the warm-up electric power generation means on a basis of a predetermined index on a necessity to warm up the fuel cell. The warm-up control means (20) controls an operation state of the fuel cell during warm-up electric power generation by the warm-up electric power generation means (20) on a basis of a correlation between the system loss required for warm-up of the fuel cell by the warm-up electric power generation means and a warm-up output required for driving of a load including the drive motor during warm-up of the fuel cell.

摘要： The present invention provides a fuel cell system capable of avoiding a disadvantage caused by the maintaining of a low-efficiency operation. The fuel cell system is configured to perform a higher-efficiency operation and a lower-efficiency operation having a larger power loss than a higher-efficiency operation. A controller of the fuel cell system controls the fuel cell system to perform the lower-efficiency operation at a predetermined low temperature to raise the temperature of a fuel cell in a shorter time than the higher-efficiency operation, and prohibits the low-efficiency operation so as to execute the higher-efficiency operation when predetermined conditions are established at the predetermined low temperature. The predetermined conditions may include a time when the generated power of the fuel cell cannot be consumed, a time when this generated power cannot be accumulated in a battery, or a time when the flooding of the fuel cell is generated. The fuel cell system avoids a disadvantage caused by the maintaining of a low-efficiency operation to improve the safety of a system operation.

摘要： A fuel cell system (10) includes: a fuel cell stack (20) which receives a fuel gas and an oxidation gas to generate a power; an air compressor (32) which supplies the oxidation gas to the fuel cell stack (20); and a controller (70) which reduces the oxidation gas flow rate supplied from the air compressor (32) to the fuel cell stack (20) in consideration of discharge from a capacitance component of the fuel cell stack (20) when decreasing the output voltage of the fuel cell stack (20). When the output voltage of the fuel cell stack (20) has dropped, the fuel cell system (10) can control a cell operation in consideration of the discharge from the capacitance component of the fuel cell stack (20) to an external load.
