Patent ID: 7615303

Claim:
A portable computer, comprising: a display unit rotatably coupled to a main unit, wherein the display unit comprises a display panel and the main unit comprises a keyboard; a liquid fuel tank; a direct methanol fuel cell (DMFC) located within an interior portion of a backside of the display panel; and a liquid supply device positioned under the keyboard and connected to both the liquid fuel tank and to the DMFC to circulate an output from the DMFC to the fuel tank, wherein the DMFC comprises: an ion exchange membrane; a plurality of anodes on a face of the ion exchange membrane, and a plurality of cathodes corresponding to the anodes and positioned on the opposite side of the ion exchange membrane; current collectors placed on each of the anodes and the cathodes, respectively; connecting wires electrically connecting the anodes and the cathodes in series; and reactant supply plates disposed on each of the anodes and the cathodes, respectively, wherein a reactant channel is formed in each unit cell region corresponding to each of the anodes and the cathodes at the reactant supply plates, wherein an inlet and an outlet of the reactant channel are formed at each unit cell region, wherein the inlets of the reactant channel are connected through a reactant inflow channel, and the outlets of the reactant channel are connected through a reactant outflow channel, wherein each of the reactant supply plates have an inlet of the reactant supply plate connected to a front end of the reactant inflow channel and an outlet of the reactant supply plate connected to a rear end of the reactant outflow channel, wherein a wicking member with a predetermined length is disposed at an inlet of the reactant channel at a side of the anode, and wherein the liquid fuel tank is placed adjacent to the DMFC.
