An oxygen supply device in a change of a load of a fuel cell vehicle is provided to expand a life span of the fuel cell vehicle by preventing the deterioration of a stack caused by oxygen shortage. An oxygen supply device in a change of a load of a fuel cell vehicle includes a fuel cell(10), an oxygen supply line(11), an air filer(12), a fan(13), a humidifier(14), an acceleration displacement sensor, an oxygen supply unit, and a control unit(20). The fuel cell generates water, heat and power by an electrochemical reaction of an oxygen and a hydrogen. The air supply line is installed on a negative electrode inlet of the fuel cell so that an air is supplied to the negative electrode inlet. The air filter and the fan are installed on the air supply line to filer and send an air. The humidifier is installed on the air supply line to humidify the filtered air uniformly. The acceleration displacement sensor senses a displacement of an acceleration pedal(21) of the vehicle. The oxygen supply unit is installed between the humidifier and the fuel cell and supplies the oxygen. The control unit receives the sensed signal from the acceleration displacement sensor and supplies the oxygen to the fuel cell by controlling an operation of the oxygen supply unit when a displacement value of the acceleration pedal is larger than a predetermined value. |
