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.

The control unit includes an average stoichiometric flow-ratio calculation part and a reactive-gas reduction part. The average stoichiometric flow-ratio calculation part calculates an average stoichiometric flow ratio by averaging stoichiometric flow ratios. A stoichiometric flow ratio is a ratio of an amount of the reactive gases supplied to the fuel cell with respect to a required amount of the reactive gases of the fuel cell in accordance with a required amount of power generation. When the average stoichiometric flow ratio is equal to or greater than a first predetermined value, the reactive-gas reduction part reduces the amount of the reactive gases supplied to the fuel cell so as to lower the stoichiometric flow ratio.

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.
