PROBLEM TO BE SOLVED: To shorten the charging time of a secondary battery of a fuel cell system in cases where starting and stopping of the fuel cell system are repeated.SOLUTION: A fuel cell system includes a fuel cell and a secondary battery. Under a condition that a command to stop the fuel cell system is received and a state of charge of the secondary battery is equal to or lower than a threshold which is a value obtained by adding a first predetermined value to a lower limit at which electric power required to stop and start the fuel cell system is supplied, a controller to control the fuel cell system controls the fuel cell system to perform forced charging from the fuel cell to the secondary battery until a state of charge reaches the threshold. After the forced charging is performed, in cases where the command to stop the fuel cell system is received within a predetermined period, the controller sets the threshold to a value obtained by adding a second predetermined value lower than the first predetermined value to the lower limit under the condition.SELECTED DRAWING: Figure 2
【課題】燃料電池システムの始動と停止が繰り返される場合における燃料電池システムの二次電池の充電時間を短縮する。【解決手段】燃料電池システムは、燃料電池と、二次電池とを備える。燃料電池システムを制御する制御部は、燃料電池システムの停止を受け、かつ、二次電池の充電量が燃料電池システムの停止及び始動のための電力を供給可能な下限値に第1の所定値を加算した値である閾値以下であることを条件に、燃料電池から二次電池への強制充電を充電量が閾値になるまで実施するように燃料電池システムを制御する。強制充電の実施後、所定期間内に燃料電池システムの停止命令を受けた場合、制御部は、上記条件において、閾値を、下限値に第1の所定値より低い第2の所定値を加算した値に設定する。【選択図】図2
