Provided is a gas temperature control apparatus for a humidifier of a fuel cell, which keeps humidity at a predetermined level by supplying preheated gas to a humidifier and enables stable performances of a fuel cell. The gas temperature control apparatus for a humidifier of a fuel cell comprises: a temperature control device(100) for heating and keeping gas at a preset temperature outside a gas pipe(10) that supplies gas to a humidifier; first and second temperature detectors(21,22) of which each detects gas temperature in the gas pipe at a gas pipe inlet(11) before the temperature control device(100) and at a gas pipe outlet(12) after the temperature control device(100); a third temperature detector(23) which detects the heating temperature of the temperature control device(100); and a controller(30) which detects each temperature from the first, second, and third temperature detectors(21,22,23) and controls driving of the heating unit(100) to keep the gas temperature of the gas pipe outlet(12) at a preset temperature. |
