PURPOSE:To secure such a cell that takes an electron out in a way of discharging energy by photosynthesis of aqueous matter, by installing both of a first cell containing the aqueous matter to be photosynthesized, a mediator and an anode electrode, and a second cell containing an acceptor and catahode electrode and being adjoined to the first cell. CONSTITUTION:An ion exchange membrane 2 is disposed in a vessel 1, forming a first cell 3 and a second cell 4 both, and the first cell 3 contains aqueous matter to be photosynthesized, a mediator 9 and an anode electrode 5 while the second cell 4 contains an acceptor 10 and a cathode electrode 6 in design. In addition, a feed port 11 and a discharge port 12 for carbonic acid gas are installed in the first cell 3. As for aqueous matter, algae, aquatic plants, seaweeds, etc., are used, and as the mediator, 2-hydroxy 1,4-naphthoquinone or triiron ethylenediamine tetraacetic acid complex mixed with the former, etc., are used. As the acceptor, an aqueous solution of potassium ferricyanide or the like is used. With this constitution, as making it photosynthesize from the photosynthetic aqueous matter, energy or one alreadly stored can be efficiently taken out in the shape of an electron. |
