Provided is a structure for improving performance of a fuel cell thermal management system according to an embodiment of the present invention. The structure for improving performance of a fuel cell thermal management system comprises: a radiator which performs heat exchange of coolant discharged from a fuel cell stack; a coolant supply pump which supplies the coolant to the fuel cell stack; a COD heater which is arranged in parallel with the radiator; a heater core which is arranged in series with the COD heater to heat an interior of a vehicle; a temperature control valve which is connected to the radiator, the coolant supply pump, and the heater core to control a flow of the coolant; and a reservoir which is arranged between a downstream of the fuel cell stack and a front end of the coolant supply pump to control a pressure of the coolant. According to the embodiment of the present invention, a flow rate of the coolant flowing to the COD heater and the radiator may be controlled by the temperature control valve.
