There is provided a fuel cell system and operation methods therefor capable of ensuring transfer to normal operation while maintaining convenience. A fuel cell system 100 includes: a cell stack 102; a secondary battery 126; a controller 142 including a CPU 158; a main switch 148; and a stop button 30b. After the main switch 148 is turned OFF, if there is no power generation stopping command from the stop button 30b, the CPU 158 stops power generation in the cell stack 102 after continuing power generation in the cell stack 102 till a charge rate of the secondary battery 126 becomes not smaller than a first threshold value. If the charge rate is not smaller than a second threshold value and is smaller than the first threshold value, generation in the cell stack 102 is stopped in response to the power generation stopping command from the stop button 30b. If the charge rate is lower than the second threshold value, power generation in the cell stack 102 is continued to charge the secondary battery 126 until the charge rate becomes not lower than the second threshold value even if a normal power generation stopping command is given from the stop button 30b.

A cooling fan (30) of a secondary battery (10) and a cooling fan (40) of a DC/DC converter (20) are arranged in parallel to share the same air discharge path (80). A temperature sensor (12) on an air intake side and a temperature sensor (14) on an air discharge side are attached to the secondary battery (10). When the cooling fan (30) is in failure, a temperature deviation between the air intake side and the air discharge side in the secondary battery (10) increases because a backflow component (95) of a discharge air (90) is generated through the discharge path (80) as the cooling fan (40) operates. Based on this phenomenon, when operation commands for both of the cooling fans (30, 40) are issued, the control circuit (50) senses a failure in the cooling fan (30) by monitoring the temperature difference between temperatures (Tb1, Tb2) detected by the temperature sensors (12, 14). Failure detection is thereby possible without providing a sensor at each of the cooling fans.

A fuel cell system comprises: a DBFC for generating a power by receiving a fuel; a PEMFC for generating a power by receiving hydrogen, a byproduct generated at an anode of the DBFC after a reaction, as a fuel; a supplementary power partially charged by a power generated at the DBFC and the PEMFC and discharging the charged power; a load sensing unit for sensing a load connected to the DBFC, the PEMFC, and the supplementary power; and a control unit for controlling a power of the DBFC, the PEMFC, and the supplementary power according to a load sensed by the load sensing unit and thereby selectively supplying to the load. According to this, hydrogen generated at the DBFC is recycled, and a load amount is sensed thus to stably correspond to a load variation, thereby maximizing a fuel usage efficiency and stably driving the system.

摘要:
In heutigen Luftfahrzeugen werden üblicherweise Behälter zur Speicherung der für den Bordbetrieb benötigten Rohstoffe, wie Sauerstoff und Wasser, verwendet. Energie wird unter Verwendung von Generatoren und Turbinen erzeugt. Gemäß einem Ausführungsbeispiel der vorliegenden Erfindung wird ein elektrochemischer Reaktor zur Erzeugung von Energie, Wasserstoff, Sauerstoff und Klarwasser bereitgestellt, der die Bordversorgung sicherstellt. Erfindungsgemäß wird hierbei freiwerdende Reaktionswärme als zusätzliche Prozesswärme im SOSE- und FP-Prozess genutzt. Weiterhin entfällt durch Nutzung des im Prozess erzeugten Wasserstoffs eine extra Entschwefelungseinheit bei der Brennstoffaufbereitung des Brennstoffs im FP. Hierdurch können große Speichervolumina und Gewicht eingespart werden.
