ABSTRACT:
A fuel supply device for direct methanol fuel cells includes a fuel tank for storing liquid fuel, a wick structure formed on the fuel tank, the wick structure for receiving the liquid fuel from the fuel tank, a sheet stack disposed on the wick structure, the sheet stack for absorbing and transferring, in an upward direction, the liquid fuel supplied to the wick structure, and an electrode plate disposed on the sheet stack for supplying, in an upward direction, the liquid fuel absorbed into the sheet stack. The fuel supply device may continuously and uniformly supply a proper amount of liquid fuel and effectively remove by-products generated in a fuel cell. Thus, a long life, efficient fuel cell may be created with the fuel supply device.
