The invention provides a fuel cell vehicle and a whole vehicle energy control system thereof, which comprises the following steps: after a power-on signal sent by a power distribution assembly is obtained, sending starting power to a high-power fuel cell engine; after a starting success signal fed back by the high-power fuel cell engine is received, idle speed power is sent to the high-power fuel cell engine; when it is judged that the current vehicle speed reaches or exceeds the preset target value, the target power, fed back by the power battery, of the first control period is sent to the high-power fuel cell engine with the preset control period as the unit, integral calculation is conducted on the whole vehicle average power in the current control period, and the set power of the next control period is generated; and when it is judged that the current vehicle speed is smaller than the preset target value and continues to be smaller than the preset detection time, idle speed power is sent to the high-power
