A fuel supply device for direct methanol fuel cells includes a fuel tank (100) for storing liquid fuel, a cavity plate (200) formed on the fuel tank, the cavity plate storing liquid fuel transferred from the fuel tank, and a nozzle (300) plate formed on the cavity plate, the nozzle plate ejecting upwardly the liquid fuel stored in the cavity plate, wherein a fuel tank body (140) of the fuel tank includes a bellows type vessel capable of contracting and expanding. Accordingly, it is possible to actively control an amount of liquid fuel supplied by the fuel supply device to a fuel cell while minimizing electric power consumption, and to effectively remove by-products, thereby improving efficiency of the fuel cell. |
