Abstract: A draining device for use with a fuel cell system includes a recovery tank, a water-absorbing article and a blower. The fuel cell system performs an electrochemical reaction to produce water and heat. The recovery tank is in communication with the fuel cell system and includes a plurality of openings and a receptacle for accommodating the water. The water-absorbing article is disposed within the receptacle of the recovery tank for absorbing and dispersing the water. The blower is in communication with the recovery tank for introducing ambient air into the recovery tank. The water is vaporized into steam by the heat produced from the electrochemical reaction of the fuel cell system. The ambient air introduced by the blower forces the steam to discharge to the surroundings via the openings of the recovery tank.
