Abstract

A fuel cell system includes an exhaust hydrogen processing device for discharging, in a dilute state, fuel electrode off-gas diluted with oxidizer electrode off-gas and air supplied from an exhaust hydrogen processing blower, which are used as a dilution processing gas. When a purge flow rate is larger than a target purge flow rate, a target air flow rate calculating section calculates as a target air flow rate a second target air flow rate which is increased from a stable generation flow rate (first target air flow rate) calculated on the basis of required electric power.
