A fuel cell power generating device comprises an electromotive unit which is formed by stacking of membrane electrode assembly which is enclosing an electrolyte film with an anode electrode and a cathode electrode and generates an electric power, a liquid fuel feed unit which supplies a liquid fuel to the anode electrode, a gas feed unit which supplies an oxidizer gas to the cathode electrode, a control unit which controls at least either the gas feed rate control for adjusting the feed rate of the oxidizer gas by the gas feed unit or the liquid fuel control for adjusting the feed rate of the liquid fuel by the liquid feed unit, at the time of satisfying either the condition in which the electromotive force of the electromotive unit is lower than a predetermined reference value, or the condition in which the predetermined time interval passes.
