Electrochemical reactor

Abstract

An electrochemical reactor includes a plurality of plate-shaped members and a plurality of passages defined by the plurality of plate-shaped members. Each plate-shaped member includes a cell including an ion conducting solid electrolyte layer, an anode layer arranged on a surface of the solid electrolyte layer, and a cathode layer arranged on a surface of the solid electrolyte layer at an opposite side to the surface at which the anode layer is arranged. The plate-shaped members are configured so that, for all of the passages, both of an anode layer of at least one plate-shaped member among the plurality of plate-shaped members defining the passages and a cathode layer of at least one other plate-shaped member among the plurality of plate-shaped members defining the passages face the passages.
