FUEL SUPPLY DEVICE FOR DIRECT METHANOL FUEL CELL, WHICH MINIMIZES POWER CONSUMPTION AND IMPROVES EFFICIENCY OF FUEL CELL

摘要

PURPOSE: Provided is a fuel supply device for supplying liquid fuel to a direct methanol fuel cell, which can supply an adequate portion of liquid fuel with high activity while minimizing power consumption. CONSTITUTION: The fuel supply device for a direct methanol fuel cell comprises: a fuel tank(100) in which liquid fuel is stored; and a cavity plate(200) formed on the top of the fuel tank(100) for storing the liquid fuel transferred from the fuel tank(100), wherein the fuel tank(100) comprises a bellow type main body(140) of the fuel tank capable of shrinking/expanding. The fuel tank(100) may be detachable by the cavity plate(200). Particularly, the main body(140) of the fuel tank has a top portion and bottom portion, the top portion having a fuel outlet.
