The invention discloses a fuel cell vehicle integrated thermal management system and a control method thereof. The system comprises a fuel cell thermal management loop, a power cell thermal managementloop, a motor thermal management loop and a passenger compartment thermal management loop. The fuel cell thermal management loop comprises a fuel cell, a radiator, a water pump, an expansion water tank, a temperature sensor and a three-way valve; the power cell thermal management loop comprises a power cell, a radiator, a water pump, an expansion water tank, a temperature sensor and a three-way valve; the invention further discloses a control method of the system. Firstly, the operation condition of the whole vehicle is judged through the environment temperature, then the opening and closingstates of the three-way valves of all the loops are comprehensively judged according to the temperature of all the loops, and therefore efficient heat utilization of whole vehicle integrated thermal management is achieved. The control mode is simple, the structure is compact, and the energy utilization rate and economy of a fuel cell vehicle are improved.
