Abstract
A temperature control apparatus and method for fuel cell system, where the apparatus includes a fuel cell stack, a first pump disposed on a first cooling line, a first radiator disposed on the first cooling line, power electronic parts, a second pump disposed on a second cooling line, a second radiator disposed on the second cooling line, a cooling fan configured to blow exterior air to any one of the first radiator and the second radiator, and a controller configured to determine an RPM of the cooling fan based on a coolant temperature at an inlet of the fuel cell stack and a first exterior air temperature, to determine a target cooling performance of the plurality of power electronic parts based on power consumptions of the plurality of power electronic parts, and to determine an RPM of the second pump based on the target cooling performance of the plurality of power electronic parts, the RPM of the cooling fan, and a second exterior air temperature.
