    摘要： A hydrogen circulation type fuel cell system equipped with an electrochemical cell executes discharging an anode off-gas with impurities being condensed toward the outside of the system at a proper timing. The fuel cell system having a circulation route so that a fuel gas containing hydrogen is supplied on the side of an anode electrode for electrochemical reaction in a fuel cell and a part or whole of an anode off-gas given from the fuel cell can be circulated on the side of the anode electrode of the fuel cell again for the electrochemical reaction, includes an electrochemical cell enabling the hydrogen in the anode off-gas flowing through the circulation route by flowing the current between electrodes to be selectively supplied on the side of the anode electrode, in which a discharge timing of discharging the anode off-gas in the inlet port electrode of the electrochemical cell toward the outside of the system is controlled based on a predetermined discharge reference determined by a correlation between electric power consumed for hydrogen transmission in the electrochemical cell and a residual hydrogen concentration in the anode off-gas discharged by a discharge unit.
