1. A method of controlling a fuel cell vehicle having a load energizable by electric power generated by a fuel cell from hydrogen supplied from a hydrogen storage device and an oxygen-containing gas supplied from an air pump, comprising the steps of:

  • performing a rate limiting control process for reducing the electric power generated by the fuel cell to reduce a frequency at which a voltage generated by the fuel cell is equal to or higher than a predetermined voltage when electric power requested by the load is lowered, and changing a rotational speed of the air pump depending on the electric power requested by the load when the electric power generated by the fuel cell is reduced.
