Abstract
A vehicleis equipped with a fuel cell systemand a secondary battery as power sources. A water level of water present on a water-covered road surface is measured by a water level sensor. When the measured water level reaches or exceeds a preset threshold value, drive control of the vehiclestops power generation by a fuel cell stack, closes a discharge valve, and enables the vehicleto be driven with output power of a motor that is actuated with electric power from the secondary battery. This arrangement effectively prevents a damage or failure of the fuel cells mounted on the vehicle moving on the water-covered road.
