摘要： The present invention provides a method for controlling the operation of a fuel cell system at low temperature that can suitably prevent flooding in a cathode of a fuel cell stack during low-temperature operation, thus improving the operation stability and durability of the fuel cell stack. In preferred embodiments, the present invention provides a method for controlling the operation of a fuel cell system at low temperature, the method comprising determining whether the temperature of a fuel cell stack reaches a normal temperature; calculating, when it is determined that the temperature of the fuel cell stack is lower than the normal temperature, a target temperature at a cathode outlet to maintain water present in a cathode of the fuel cell stack in a vapor phase based on information related to an operation state of the fuel cell stack detected by an operation state detection means; and calculating a target amount of coolant based on the calculated target temperature at the cathode outlet and the information related to the operation state of the fuel cell stack, and controlling the amount of coolant supplied to the fuel cell stack based on the calculated target amount of coolant.
