摘要： A fuel cell system includes a fuel cell, an oxidant gas passage, a cathode off-gas passage, a fuel gas passage, a circulation passage, an anode off-gas passage, a fuel shutoff valve, a supply device, a humidifier and a control device. The supply device supplies a scavenging gas, which is for scavenging the fuel cell, to the anode and the cathode. The humidifier humidifies the scavenging gas. The control device controls the supply device when the fuel cell is turned off so that supply of the fuel gas to the anode is shut off and the scavenging gas is supplied to the anode and the cathode, wherein supply of the scavenging gas to the cathode is conducted through the humidifier.

摘要： A fuel cell system comprises a humidifier which can humidify a fuel cell even when humidification has become insufficient at start-up of the fuel cell and during normal operation thereof. A water collecting apparatus which collects water in the exhaust gas of the fuel cell, and an auxiliary humidifier which humidifies the gas supply by using collected water from the water collecting apparatus, are provided separate to the water-permeable-type humidifier. The water collecting apparatus comprises a vapor/liquid separator and a collected water storage tank, and the auxiliary humidifier comprises a check valve, a collected water supply pump, an auxiliary humidification pipe, and an injector. The collected water in the collected water storage tank is transferred by a collected water supply pump, atomized by the injector, and supplied to the intake side of the fuel cell.

摘要： A control system for a fuel cell includes a reactant gas supplying unit which supplies a reactant gas to the fuel cell, and a discharged reactant gas flow control unit disposed at an outlet of the fuel cell. The discharged reactant gas flow control unit includes a first control valve and a second control valve disposed in parallel with the first control valve. The second control valve has a different pressure-flow control characteristic as compared with the first control valve. Only the second control valve controls the flow rate of a discharged reactant gas until the flow rate exceeds a predetermined value, and the second control valve together with the first control valve controls the flow rate of the discharged reactant gas when the flow rate of the discharged reactant gas exceeds the predetermined value.
