CHEMICAL REACTION DEVICE

摘要

This chemical reaction device is equipped with: an electrolysis tank (21) containing an electrolyte solution (23); a laminate (10) contained inside the electrolysis tank, and provided with a first electrode (16) situated on the light incidence side, a second electrode (11) situated on the opposite side from the light incidence side, and a photovoltaic power layer (15) formed between the first electrode and the second electrode, for carrying out charge separation through light energy; an external power supply (32) electrically connected through a first switching element (31) to between the first electrode and the second electrode; a power demand unit (34) electrically connected through a second switching element (33) to between the first electrode and the second electrode, and connected in parallel to the external power supply; and a switching element controller (41) for on/off control of the first switching element and the second switching element.
