ELECTROLYTIC CELL UNIT, ELECTROLYTIC CELL DEVICE, HYDROCARBON PREPARING SYSTEM, AND METHODS FOR MANUFACTURING AND USING ELECTROLYTIC CELL UNIT

摘要

Provided is an electrolytic cell unit (U) which can efficiently perform electrolysis of water and carbon dioxide. The electrolytic cell unit (U) is configured to at least comprise: an electrolytic cell (1) in which an electrode layer (2) and a counterpart electrode layer (3) are formed with an electrolytic layer (1a) therebetween; and a discharge path (5a) for discharging hydrogen generated from the electrode layer (2), wherein the electrolytic cell (1) is formed on a support body (4) in a thin layer shape, and a reverse water gas shift reaction unit (20), which generates carbon monoxide by using carbon dioxide and the hydrogen through a reverse water gas shift reaction, is provided to at least a portion of the discharge path (5a).
