Direct oxidation fuel cell

A direct oxidation fuel cell comprising one or more electricity generators, each of the electricity generators having an membrane-electrode assembly and an anode member and a cathode member in close contact with respective sides of the membrane-electrode assembly, the membrane-electrode assembly being between the anode member and the cathode member for generating electrical energy and water by a reaction of a fuel and oxygen,

• wherein the cathode member comprises a plurality of air vents having diameters gradually increasing in a direction from a surface of the cathode member closely contacting the membrane-electrode assembly to a surface of the cathode member contacting the atmosphere, water discharge lines at the surface of the cathode member contacting the atmosphere to discharge water condensed in the air vents, and absorbing members having a hydrophilic property for absorbing water and being at the water discharge lines, and
• wherein a same one of the water discharge lines extends between and is coupled to two parallel columns of the air vents.
