POWER GENERATION SYSTEM

To provide a highly efficient power generation system which can also be built in a portable device.SOLUTION: A power generation system comprises: liquid; a porous power generator; a container accommodating the liquid and the porous power generator; and a power collection unit connected with the porous power generator to collect current generated by the porous power generator. Then, a contact amount between liquid and a power generation surface per unit volume of the power generator can be increased to provide a highly efficient power generation system since the porous power generator comprises a power generation layer at least on an inner surface of a porous base material having a continuous hole, and is constituted so that the porous power generator and the liquid are relatively moved, and the liquid moves in the continuous hole to generate power.SELECTED DRAWING: Figure 3 【課題】ポータブル機器にも内蔵できる高効率な発電システムを提供する。【解決手段】本発明の発電システムは、液体と、多孔質発電体と、上記液体と上記多孔質発電体とを収容した容器と、上記多孔質発電体に接続し、上記多孔質発電体が発電した電流を集電する集電部と、を備える。そして、上記多孔質発電体が、連通孔を有する多孔質基材の少なくとも内表面に発電層を有し、上記多孔質発電体と上記液体とを相対的に移動させ、上記連通孔内を上記液体が移動して発電することとしたため、発電体の単位体積当たりの液体と発電面との接触量を増大し、高効率な発電システムを提供できる。【選択図】図３
