Provided is an air humidification device for a fuel cell system, which allows air humidification by using waste heat generated from the reaction in a reformer, increases the efficiency of a fuel cell system, and reduces the cost required to manufacture and maintain a fuel cell system. The fuel cell system comprises; a stack unit(130) having a fuel electrode and an air electrode and generating electricity via electrochemical reactions between hydrogen and oxygen; a fuel supply unit(110) having a reformer for purifying hydrogen supplied from a fuel source and supplying the fuel to the fuel electrode of the stack unit; an air supply unit for supplying air to the air electrode of the stack unit; and a water feeding unit for circulating and supplying water so that the fuel supply unit is adequately cooled. The fuel cell system further comprises an air humidification unit(160) so that the water discharged after cooling the reformer(111) is allowed to be in contact with the water supplied to the stack unit to accomplish air humidification. |
