Patent ID: 7722976

Claim:
A power generation device comprising: (i) a fuel package, including: a vessel having an interior space, and a flow-out opening and a flow-in opening that lead to the interior space; a liquid fuel filled in a region of the interior space at a side of the flow-out opening in the vessel; and a follower that separates the liquid fuel from a region of the interior space at a side of the flow-in opening, wherein the follower comprises a high viscosity fluid that has a higher viscosity than the liquid fuel, and (ii) a power generation module that includes a suction opening that is freely connected to the flow-out opening of the fuel package, and a first exhaust opening that is freely connected to the flow-in opening of the fuel package, wherein the power generation module generates electric energy using the liquid fuel supplied from the fuel package, and exhausts a part of a product generated from the liquid fuel by chemical reaction, from the fist exhaust opening.
