摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system that can suppress the fluctuation range of the power storage amount stored in a power storage device so as to suppress deterioration of the power storage device, while improving the generation efficiency of the fuel cell.SOLUTION: A fuel cell system 10 comprises a controller 60 for controlling the generated power FP by a fuel cell stack 20.

The controller 60, when an SOC of the battery 52 is smaller than the prescribed target state of charge TSOC, suppresses a decrease of the generated power FP at a time when a required power FP is decreased. Thus, a control for adjusting the stored power is performed to suppress a fluctuation range of the SOC.

Exhaust water vapor amounts on an anode side and a cathode side are calculated based on the consumed oxygen amount, the consumed hydrogen amount, and measured results with flow meters 30-96. A budget of moisture amount which is the moisture variation amount is calculated based on the produced water amount and the exhaust water vapor amount.
