ABSTRACT:
A direct oxidation fuel cell is provided. A direct oxidation fuel cell includes one or more electricity generators which have a membrane-electrode assembly and anode and cathode members disposed in close contact with respective sides of the membrane-electrode assembly interposed therebetween in order to generate electrical energy and water by a reaction of a fuel and oxygen. The cathode member includes a plurality of air vents of which diameters gradually increase in a direction from a surface of the cathode member closely contacting the membrane-electrode assembly to a surface thereof contacting the atmosphere. Water discharge lines are formed at the surface contacting the atmosphere to discharge water condensed in the air vents. Absorbing members which have a hydrophilic property for absorbing water are formed at the water discharge lines.
