Abstract:
A control device of fuel cell system includes an anode gas circulation flow rate control unit configured to control the anode gas circulation flow rate on the basis of the wet/dry state of the electrolyte membrane detected by the wet/dry state detecting unit, a priority setting unit configured to set priority levels of a normal manipulation to a plurality of physical quantities manipulated by the wet/dry state control unit, and the anode gas circulation flow rate control unit includes an anode gas circulation flow rate limiting unit configured to limit a change rate per unit time of the anode gas circulation flow rate during a transient operation for changing the wet/dry state of the electrolyte membrane, and a control quantity compensating unit configured to, if the change rate is limited, compensate an insufficiency in a control quantity of the wet/dry state due to the limitation of the anode gas circulation flow rate, the compensation being carried out by manipulating a physical quantity with a lower priority level of the normal manipulation than a priority level of the normal manipulation of the anode gas circulation flow rate set by the priority setting unit.

Claim (Index 11):
A control device for fuel cell system for generating power according to a request of a load by supplying anode gas and cathode gas to a fuel cell, the fuel cell system being an anode gas circulation-type fuel cell system provided with:\n an anode gas circulation passage for supplying anode off-gas discharged from the fuel cell and the anode gas, which is to be supplied to the fuel cell, to the fuel cell by mixing the anode off-gas and the anode gas; a wet/dry state detecting unit configured to detect a wet/dry state of an electrolyte membrane of the fuel cell; and a wet/dry state control unit configured to control the wet/dry state of the electrolyte membrane by manipulating a plurality of physical quantities including a circulation flow rate of the anode gas flowing in the anode gas circulation passage; the control device, comprising: an anode gas circulation flow rate control unit configured to control the anode gas circulation flow rate on the basis of the wet/dry state of the electrolyte membrane detected by the wet/dry state detecting unit; and a priority setting unit configured to set priority levels of a normal manipulation to the plurality of physical quantities to be manipulated by the wet/dry state control unit; wherein, the anode gas circulation flow rate control unit includes: an anode gas circulation flow rate limiting unit configured to limit a change rate per unit time of the anode gas circulation flow rate during a transient operation for changing the wet/dry state of the electrolyte membrane; and a control quantity compensating unit configured to, if the change rate of the anode gas circulation flow rate is limited by the anode gas circulation flow rate limiting unit, compensate an insufficiency in a control quantity of the wet/dry state due to the limitation of the anode gas circulation flow rate, the compensation being carried out by manipulating a physical quantity with a lower priority level of the normal manipulation than a priority level of the normal manipulation of the anode gas circulation flow rate set by the priority setting unit.
