摘要： A fuel cell system includes an idle stop unit, a discharger, a power-generation-state memory, and an initial-current-value setter. The idle stop unit is configured to stop a supply of the reactant gas to a fuel cell. The discharger is configured to allow the fuel cell to generate the electric power with the reactant gas remaining in the fuel cell after the idle stop unit stops the supply of the reactant gas and is configured to discharge electric current to a current receiver. The power-generation-state memory is configured to store a power-generation state of the fuel cell immediately before the idle stop unit stops the supply of the reactant gas. The initial-current-value setter is configured to set an initial current value of the fuel cell discharged by the discharger on a basis of the power-generation state of the fuel cell stored in the power-generation-state memory.

摘要： The present invention provides a fuel cell system and a control method thereof that performs a scavenging process when the fuel cell is stopped, whereby stable electrical power production is ensured after startup, and faster startup is possible. The fuel cell system performs the scavenging process in which scavenging gas is supplied into an anode gas system when the fuel cell is stopped. When a startup request for the fuel cell is detected while the anode scavenging process is being performed, the concentration of hydrogen in the anode gas is detected, and then whether to continue the anode scavenging process and prohibit the fuel cell from starting, or to suspend the anode scavenging process and allow the fuel cell to start is determined based on this detected concentration of hydrogen in the anode gas system.

摘要： A controller of a fuel cell system includes an anode gas replacement apparatus, a stoppage time detection apparatus, and a cathode gas flow rate control apparatus. The anode gas replacement apparatus replaces hydrogen in an anode gas channel using an anode gas supply apparatus. The stoppage time detection apparatus detects a stoppage time during which operation of the fuel cell stack is stopped. When the anode gas replacement apparatus replaces the hydrogen, the cathode gas flow rate control apparatus changes the flow rate of the cathode gas supplied from the cathode gas supply apparatus depending on the stoppage time.
