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.

摘要： A fuel cell system includes an ECU that sets the fuel cell stack to a state of idling stop by lowering both a revolution speed of an air pump and a discharge current value of the fuel cell stack to less than during idling power generation within a range larger than 0, in response to a predetermined idling stop initiation condition having been satisfied during idling power generation. The ECU decreases the discharge current value further as the lowest cell voltage value CV_low of the fuel cell stack decreases so that the lowest cell voltage value CV_low does not fall below a cancellation threshold B, with an event of the lowest cell voltage CV_low of the fuel cell stack having fallen below the cancellation threshold B as a cancellation condition of idling stop.
