Abstract
A cell stack device includes at least one cell and at least one conductive member. The cell includes an element portion. The conductive member includes a base member containing chromium, a first layer containing an oxide containing zinc, and a zinc spinel portion located at the interface between the base member and the first layer. The first layer includes a first region facing the element portion. A first overlap area ratio, at which the zinc spinel portion located at a first interface between the first region and the base member overlaps with the first interface, is less than a second overlap area ratio, at which the zinc spinel portion located at a second interface between a second region where the surface of the first layer is exposed to an oxidizing atmosphere and the base member overlaps with the second interface.
