Abstract
Provided is a voltage control device of a fuel-cell vehicle capable of securing good acceleration responsiveness while suppressing battery deterioration even when a vehicle acceleration request is made in the situation where the output from a battery is restricted. When determining that electric power suppliable from a secondary battery to an air compressor is less than a lower limit of an acceleration maintaining-electric power of the air compressor, a voltage control device of a fuel-cell vehicle maintains a state where electric power generated by a fuel cell is consumed by an electric power drive, and supplies the electric power consumed by the electric power drive to the air compressor when a vehicle acceleration request is made.
