Abstract: A fuel cell system according to an embodiment of the present invention comprises: an air manifold for supplying or discharging air; a fuel gas manifold for supplying or discharging fuel gas; a stack part for generating electricity using the air and the fuel gas supplied by the air manifold and the fuel gas manifold; and an injection array arranged along the inside of the air manifold and the fuel gas manifold and having a nozzle for spraying air or fuel gas. Therefore, the total flow variation is reduced by uniformly supplying hydrogen or air through the nozzle from the injection array, and the stability of power generation is improved and the operation of an air blower can be maintained stably as high-pressure gas sprayed from the nozzle removes locally-generated water. In addition, the load of an air compressor or a recirculating blower can be maintained at a predetermined minimum by supplying air or hydrogen to the channel of a cell through the injection array. In addition, water can be removed effectively by supplying air, which has not passed a humidifier in shutdown logic, to a cell in a stack part through the injection array in the shape of pulse. In addition, the whole durability can be improved by supplying a very small amount of hydrogen to an anode and a cathode through the injection array while a fuel cell has not operated for a long period. Moreover, the whole durability can be improved by supplying a very small amount of hydrogen through the injection array before the operation of the air compressor during start, thus inhibiting the generation of high voltage.
