Claim:
1. A control method for a fuel cell system, including a driving unit configured to run a mobile body by supplying an electric power, a fuel cell stack configured to supply an electric power to the driving unit for running, a fuel supply unit configured to supply fuel necessary for electric power generation of the fuel cell stack, comprising: computing a stack output-response request, the stack output-response request being an electric power response required from the fuel cell stack to return from an idle-stop; setting up a lower limit of a stack setup-voltage during the idle-stop as a stack voltage during execution of the idle-stop that becomes higher as the stack output-response request becomes larger and becomes lower as the stack output-response request becomes smaller; and executing a recovery operation in which the fuel or air is supplied when an actual voltage of the fuel cell stack becomes lower than the lower limit of the stack setup-voltage during the idle-stop.
