摘要： A fuel cell system comprises a fuel cell stack, a cell voltage monitor, a hydrogen tank, a hydrogen supply channel, an ejector, a hydrogen off-gas channel, a purge valve, a compressor, an air supply channel, a pressure control unit for controlling air pressure, a pilot pressure input channel branching off from the air supply channel and inputting the air pressure to the ejector as pilot pressure, and a control unit for controlling the purge valve and the pressure control unit. The ejector includes a pressure control mechanism which increases the ejector's secondary-side pressure by increasing the area of the nozzle's ejecting hole when the pilot pressure input from the pilot pressure input channel rises. When electricity generation status of the fuel cell stack is judged to be poor, the control unit opens the purge valve after raising the air pressure and the pilot pressure by using the pressure control unit.

摘要： A reaction gas is supplied to a cathode side of a fuel cell at a flow rate higher than that for a usual operation of the fuel cell to thaw the fuel cell system at startup in a freezing state of the system when the system has experienced a temperature lower than an operation temperature of an anode off-gas. A thawing state of the system is detected on the basis of at least two of temperatures of the anode off-gas, a cathode off gas, and a radiator liquid of the fuel cell to control supplying the reaction gas to the cathode side at a usual operation flow rate. An actual increase rate of the temperature of the anode off-gas is obtained and an increase rate of the temperature of the anode off-gas is calculated from the self-heating value to be compared to determine the thawing state.
