Title:
COMPOSITE, AND ELECTROCHEMICAL REACTION CELL STACK
Document Type and Number:
WIPO Patent Application WO/2019/207856
Kind Code:
A1
Abstract:
The present invention suppresses a reduction in strength due to localized warping at the surface of a composite. This composite includes: an electrolyte layer containing a solid oxide; and at least one electrode selected from an air electrode disposed on one side in a first direction in the electrolyte layer and a fuel electrode disposed on the other side in the first direction in the electrolyte layer. Any of the surfaces of the composite in the first direction satisfies a first requirement that the curvature as viewed in the first direction, on the basis of any 3 points arranged at 5 mm intervals, is less than 0.0013 (1/mm), and that the curvature as viewed in a second direction which is perpendicular to the first direction, is the inverse of the radius of an imaginary circle passing through any three points.
