NOVELTY - A fuel cell (100) comprises an air supply unit (60); a fuel supply unit (40); a membrane electrode assembly (MEA) (50) disposed between the air and fuel supply units; an absorbing member (70) coupled to the air supply unit for absorbing moisture. The absorbing member is disposed between the air supply unit and the MEA. The air supply unit supplies air to the MEA, and is exposed to atmospheric air. The absorbing member includes a porous layer formed of a porous medium material for storing moisture, and a moisture absorption layer formed on the porous layer for absorbing moisture.    USE - For generating electric energy.    ADVANTAGE - Fuel cell including absorbing member that provides improved performance and reliability of the fuel cell and effectively absorbs moisture, and blocking of airflow path by the moisture is prevented. The absorbing member absorbs moisture generated inside the outer case. Therefore, the damage of the device coupled to the fuel cell can be prevented. Since the electricity generation unit of fuel cell has absorbing member that can absorb moisture generated by the electrochemical reaction between the fuel and the oxygen, the blocking of the air holes of the air supply unit by the moisture can be prevented. Therefore, atmospheric air can be effectively supplied through the air holes of the air supply units and thus the performance efficiency and reliability of the fuel cell can be further improved. In addition, since the air supply units of the electricity generation unit are exposed to atmospheric air through the both opposite surface of the fuel cell main body, the air can be effectively supplied to the air supply units regardless of the user environment. Hence, the heat generated from the air supply units can be effectively dissipated. As a result, the output of the electric energy can be maximized and the hazard that may be caused by the increase of the temperature of the fuel cell main body can be avoided, thus improving the performance and reliability of the fuel cell.
