Document Type and Number:
WIPO Patent Application WO/2021/172481
Kind Code:
A1
Abstract:
This cell stack device is provided with at least one cell and at least one electroconductive member. The cell comprises an element part. The electroconductive member comprises: a base material that contains chromium; a first layer that contains an oxide containing zinc; and a zinc spinel part that is positioned at the interface between the base material and the first layer. The first layer has a first region that faces the element part. The ratio of a first area where the zinc spinel part positioned at a first interface between the first region and the base material overlaps with the first interface is smaller than the ratio of a second area where the zinc spinel part positioned at a second interface between the base material layer and a second region, where the surface of the first layer is exposed to an oxidizing atmosphere, overlaps with the second interface.
