摘要： A fuel cell system and an idle stop controlling method for the fuel cell system. The fuel cell system includes: a fuel gas supply means for supplying fuel gas; an oxidant gas supply means for supplying oxidant gas; a fuel cell to which the fuel gas and the oxidant gas are supplied for generation of electricity; an idle stop means for stopping generation of electricity by the fuel cell to perform idle stop; and an unstable state detection means for detecting whether the generation of electricity by the fuel cell is unstable. If the unstable state detection means detects that generation of electricity by the fuel cell is unstable, idle stop by the idle stop means is prohibited so that the fuel cell continues to generate electricity.

摘要： To provide a fuel cell moving body that can extend travel distance by the battery when fuel cell failure has occurred. A fuel cell vehicle 1 includes a fuel cell 10, a battery 11 and a control device 30. The control device 30 includes a liquid droplet removal scavenge portion 34 and a dry scavenge portion 35. The control device 30 judges whether power generation continuation of the fuel cell 10 is possible during the running. When the continued power generation is judged to be possible, the power generation continues, and after running, the liquid droplet removal scavenge portion 34 and the dry scavenge portion 35 perform the scavenge. When continued power generation is judged to be impossible, power generation is stopped, the fuel cell vehicle is run by the battery 11 and the liquid droplet removal scavenge portion 34 performs scavenge.

摘要： Upon stop of electric power generation of a fuel cell a hydrogen shutoff valve is closed, and a cathode is purged. At the same time, an air introducing valve and the purge valve are opened. The air taken in by the compressor is introduced into the anode through the air introducing tube to exhaust the hydrogen remaining in the anode to replace the hydrogen with the air. When the replacement of the hydrogen with the air has been finished, the compressor is turned off and the air introducing valve and the purge valve are opened. After that, if a temperature of the fuel cell is determined to be equal to or lower than a threshold “a”, a cathode-prioritized purge and an anode-prioritized purging are performed.

摘要： A fuel-cell system 1 includes: a fuel cell 13 configured to generate electricity through reaction between hydrogen gas and air; a compressor 12 configured to supply air as a scavenging gas to a reactant gas path 13a of the fuel cell 13; a control part 18 configured to control an amount of air supplied from the compressor 12 to the fuel cell 13 to perform scavenging of the fuel cell 13; and pressure sensors P1 and P2 configured to monitor a pressure drop in the reactant gas path 13a of the fuel cell 13.
