FUEL MIXING TANK WITH PREVENTING HONEYCOMB PLATE OF FUEL SURGING FOR DIRECT METHANOL FUEL CELL SYSTEM AND DIRECT METHANOL FUEL CELL SYSTEM COMPRISING THE SAME

摘要

The present invention relates to a fuel mixing tank for a direct methanol fuel cell system having a fuel flow preventing device installed thereon and a direct methanol fuel cell system including the same. The fuel mixing tank of the present invention receives raw liquid methanol fuel, cathode discharged material, and anode discharged material respectively from a fuel tank, a cathode, and an anode and provides the anode with mixed fuel that is made by mixing the same. The fuel mixing tank comprises a top chamber and a bottom chamber that are separated into a top and a bottom by means of a separation plate. The top chamber comprises: a cathode discharged material inlet through which the cathode discharged material is supplied; and a gas outlet through which gas is discharged to the outside. The bottom chamber comprises: an anode discharged material inlet through which the anode discharged material is supplied; a raw liquid methanol inlet through which the raw liquid methanol fuel is supplied from the fuel tank; and a fuel supply hole through which the mixed fuel is supplied to the anode. The separation plate comprises: a water supply channel that is installed as a pipe for penetrating the separation plate in order to have the top disposed in the top chamber and the bottom disposed in the bottom chamber; and a gas transferring unit for transferring the gas in the bottom chamber to the top chamber, wherein a porous flow preventing plate is installed inside the bottom chamber so that the mixed fuel can be moved up and down.
