The present invention relates to a thermal management system for fuel cell vehicles, comprising: a first line which comprises a coolant pump and a fuel cell stack; a second line which comprises a coolant heater and a PCM, and is connected to the first line to form a first loop where the coolant pump, the stack, the coolant heater and the PCM are arranged; a third line which comprises a radiator, and is connected to the first line to form a second loop where the coolant pump, the stack and the radiator are arranged; and an opening/closing valve which opens/closes the first, second and third lines, respectively, so that the coolant circulates at least one loop between the first and second loops. The PCM is provided to heat-exchange with the coolant heater and the coolant, respectively. According to the present invention, the time required for cold start can be reduced.
