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.

Mobile body mounted with fuel cell

A vehicle is equipped with fuel cells that is fastened to multiple side framesarranged in parallel to each other and along a moving direction of the vehicle. The vehicle includes a support assembly arranged to span between the multiple side frames, a first fixation unit arranged to fasten the support assembly to the respective side frames, and a second fixation unit arranged to fix the fuel cells on the support assembly. This arrangement desirably reduces the influence of an external force applied to the fuel cells mounted on the vehicle and prevents an increase in total weight of the vehicle or a decrease in mounting space of the fuel cells.

Vehicle and fuel cell vehicle-mounting method

A vehiclehas two pipingsandarranged to discharge an exhaust gas from a fuel cell stackto the outside of the vehicle. An outlet provided at an end of the pipingis located at an underfloor position in a rear portion of the vehicle, while an outlet provided at an end of the pipingis located at a roof rear end of the vehicle. When the outlet provided at the end of the pipingis blocked or when there is a potential for such blockage, the outlet provided at the end of the pipingis used to discharge the exhaust gas from the fuel cell stackto the outside of the vehicle. This arrangement ensures continuous drive of the vehicleeven in a specific environment where any of various obstructing objects as the cause of blockage of the outlet is present in the surroundings of the vehicle
