<P>PROBLEM TO BE SOLVED: To provide a fuel supply device for a direct methanol fuel cell capable of supplying a required and sufficient amount of fuel to a power generation unit without using a pump. <P>SOLUTION: In a fuel supply device 7 for a direct methanol fuel cell 1 that is configured to supply methanol aqueous solution stored in a fuel tank 2 via a fuel supply tube path 4 to the anode side of a power generation unit 5, a variable capacity fuel tank 7 is disposed along the fuel supply tube path 4, the variable capacity fuel tank 7 increasing/decreasing its volume according to its elastic deformation and storing pre-determined amount of the methanol aqueous solution therein. The variable capacity fuel tank 7 extrudes the methanol aqueous solution stored therein by elastically deforming its shape so as to reduce its volume and supplies the solution to the anode side of the power generation unit 5, and replenishes its inside with the methanol aqueous solution stored in the fuel tank 2 by vacuuming while restoring its shape. <P>COPYRIGHT: (C)2013,JPO&INPIT |
