摘要：PURPOSE: An apparatus for removing a water film of a fuel cell and its preparation method are provided, to remove the water film formed on a cathode for maintaining the electric power generating performance to be constant. CONSTITUTION: The generator of a fuel cell comprises an anode where fuel is supplied through a fuel supply line(103), a cathode where air humidified at a humidifier is supplied through a air supply line(107), and a separator between the anode and the cathode, and the electricity is generated by the electrochemical reaction between the fuel and the humidified air. The method comprises the steps of detecting the output state of a generator, and directly supplying air inside the flow path of a cathode through a bypass line(118) which is set to go round a humidifier(111) if the detected value is below a set value, thereby removing the water film formed on the surface of a cathode.
