Interconnect - Electrochemical Reaction Single Cell Complex, Electrochemical Reaction Cell Stack and Interconnect - Electrochemical Reaction Single Cell Complex

摘要

Thereby suppressing the occurrence of cracks and deformation of the interconnector. The interconnector-electrochemical reaction single cell complex comprises an electrochemical reaction single cell and an interconnect. A plurality of combinations of the convex portions projecting in the first direction and the concave portions arranged in the convex portion side on the opposite side of the convex portions in the first direction are formed in the interconnection. In at least one of the plurality of combinations, in the first direction, the bottom of the concave portion is located on the opening end side of the concave portion than the base end of the convex portion, and in the cross section parallel to the first direction, And the width t1 of the concave portion in the second direction is smaller than the width t2 of the convex portion in the second direction.
