A diluted fuel mixing tank for a direct methanol fuel cell is provided to minimize the capacity of a fuel tank, thereby reducing the size of a fuel cell system and maximizing the efficiency of fuel. A diluted fuel mixing tank comprises a lower bath(11) which has an upward open type lower space(R1), is provided with a first injection hole(I1) for injecting the pure methanol of a pure methanol tank into the lower space and a second injection hole(I2) for injecting the fluid discharged from the one side of a fuel cell, and is provided with a first discharge hole(E1) formed at the position higher than the first and second injection holes for supplying the diluted fuel generated at the lower space to the fuel cell; a partition wall(12) which is combined with the total internal interference of the lower bath and has a water inflow hole and a gas inflow hole(H2) provided with a vertically erected gas pipe(P1); and an upper bath(13) which is extended from the upper part of the lower bath, has a downward open upper space(R2) divided with the lower space by the partition wall, and is provided with a third injection hole(I3) for injecting the water and air discharged from the other side of the fuel cell and a second discharge hole(E2) for discharging the excessive of water and carbon dioxide gas in fluid. |
