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 20):
A control method for fuel cell system configured to generate power by supplying anode gas and cathode gas to a fuel cell, being provided with 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, comprising:\n detecting a wet/dry state of an electrolyte membrane of the fuel cell; controlling an anode gas circulation flow rate of the anode gas circulation passage on the basis of the detected wet/dry state of the electrolyte membrane; and controlling the wet/dry state of the electrolyte membrane by manipulating a plurality of physical quantities including the anode gas circulation flow rate, each of priority levels of a normal manipulation being set to the plurality of physical quantities; wherein, controlling of the wet/dry state of the electrolyte membrane includes: limiting a change rate per unit time of the anode gas circulation flow rate during a transient operation of changing the wet/dry state of the electrolyte membrane; and compensating an insufficiency in a control quantity of the wet/dry state insufficient due to the limitation of the anode gas circulation flow rate by manipulating the physical quantity having a lower priority of the normal manipulation than that of the anode gas circulation flow rate if the change rate of the anode gas circulation flow rate is limited.
