PURPOSE:To make a control apparatus more reasonable and to reduce exhaust humidity by exhausting surplus air through a flow regulating means and a bifurcate pass in an exhausting side of a condensate condenser, and controlling reaction and burning air quantity corresponding to output current change. CONSTITUTION:Three-bypass valves 22, 23 (flow regulating means) are provided in discharging sides of reaction and burning air blowers 7, 8, and are connected to an outlet side of an exhaust 5E of a condensate condenser 5 through a common bifurcate pass 21. Blowers 7, 8 are driven at a fixed speed by an AC motor, opening number of valves 22, 23 are controlled, corresponding to a detected current of a current detector 3A, by driving voltages V1, V2 generated by an output control part 9. Reaction air 7A with a quantity in which an oxygen consumption rate is kept constant corresponding to change of a load is supplied to air electrodes of a fuel cell 2. Accordingly, humidity of exhaust 5E is reduced by surplus air 21A branched out to the pass 21, a control apparatus can be made more reasonable. |
