Abstract
A fuel cell system () includes a hydrogen supply valve () that controls a supply of the anode gas into an anode system, a purge valve () that discharges an off-gas from the anode system, a pressure detecting unit () configured to measure a pressure inside the anode system, and a purge flow rate estimating unit () configured to estimate a purge flow rate of the off-gas discharged from the anode system through the purge valve () based on a pressure decrease in a purge valve open state and a pressure decrease in a purge valve close state when an anode gas supply into the anode system stops.
