Electrochemical reaction cell stack, interconnector-electrochemical reaction single cell complex and method of manufacturing electrochemical reaction cell stack

摘要

Interference between adjacent conductive members is suppressed. The electrochemical reaction cell stack includes a plurality of single cells and a plurality of flat conductive members arranged in the first direction. The plurality of conductive members have a first surface on one side in a first direction that includes a first conductive member including a first flat portion and a convex portion, and a first surface with respect to the first conductive member. A second surface located on one side of the first direction and facing the first surface of the first conductive member, the second surface including a second flat portion and a concave portion facing the convex portion; And 2 conductive members. The thickness in the first direction of the second conductive member is thicker than the thickness in the first direction of the first conductive member. The depth dimension of the concave portion from the second flat portion in the second conductive member in the first direction is the protrusion of the convex portion in the first direction from the first flat portion in the first conductive member. Greater than length.
