ABSTRACT:
A system controller100controlling an electric power generation system of a fuel cell powered vehicle realizes functions as a fuel-cell power-generation response time estimation section101, by which power-generation response time of a fuel cell1is estimated, an optimum motor-output response time estimation section102, by which an optimum output response time of a drive motor22is estimated, and a motor-output response time control section103for controlling an output response time of the drive motor22. The power-generation response time of the fuel cell is estimated based on an atmospheric pressure detected by an atmospheric sensor35and depending on this power-generation response time, the output response time of the drive motor is controlled so as to limit a rate of change in a torque command value for the drive motor such that the output response time of the drive motor is not shorter than power-generation response time of the fuel cell.
