摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system capable of improving output performance of a fuel cell directly after startup.
SOLUTION: A control device 7, when an operation start of the fuel cell system 1 is commanded, gets access to a measurement impedance memory 70, and reads out a measured impedance stored at the previous system stoppage. Then, the control device 7 compares the measured impedance read out and a reference impedance stored in a reference impedance memory 51. If the measured impedance exceeds the reference impedance, the control device 7 judges that a drying process is already done at the system stoppage, and puts the system Ready On after executing humidification treatment.

摘要： PROBLEM TO BE SOLVED: To shorten the time required to stop a fuel cell system, and to prevent freezing of a fuel cell.
SOLUTION: The fuel cell system 1 includes a controller 7 for controlling the operation of the fuel cell 2. The controller 7 operates the fuel cell 2 in a dry state depending on the state quantity (for example, impedance) of the fuel cell 2 during operation. The controller 7 can operate the fuel cell 2 in the dry state before a system stop command is issued. The controller 7 can switch the fuel cell 2 from the operation in the dry state to operation in a wet state when the required output of the fuel cell or the velocity of a vehicle 100 becomes equal to or higher than a predetermined value.
