Methods of Making Interconnector-Electrochemical Reaction Single Cell Composites, Electrochemical Reaction Cell Stacks, and Interconnect-Electrochemical Reaction Single Cell Composites

摘要

Suppresses the occurrence of cracking or deformation of the interconnect The interconnector-electrochemical reaction single cell complex includes an electrochemical reaction single cell and an interconnector. In the interconnector, a plurality of combinations of convex portions protruding in the first direction and concave portions disposed on opposite sides of the convex portions in the first direction and recessed toward the convex portions are formed. In at least one of these plural combinations, in the first direction, the bottom of the concave portion is located on the open end side of the concave portion rather than the base end of the convex portion, and in the cross section parallel to the first direction, the concave portion is in the first direction. It is located in the range of the width | variety t2 of the convex part in a 2nd direction orthogonal to, and the width | variety t1 of the recessed part in a 2nd direction is smaller than the width t2 of a convex part.
