Abstract

An electrochemical reaction device comprises: an anode unit to oxidize water and thus generate oxygen; a cathode unit to reduce carbon dioxide and thus generate a carbon compound and hydrogen; a separator separating the anode and cathode units; and a power supply connected to the anode and cathode units, the cathode unit including: a porous member having a first surface and a second surface; a flow path plate facing the first surface; and a reduction catalyst on the second surface, and the flow path plate including: a flow path through which a target gas containing the carbon dioxide flows; and a porous film separating a first space and a second space inside the flow path and being permeated with an ionic liquid, the ionic liquid being configured to separate the carbon dioxide from the target gas.
