Abstract
In at least one sealing member () disposed between at least two neighboring cells of a plurality of cells () in this cell stack device, the angle θ is 45° or less, where the angle θ is defined by an angle between a vertical line drawn from a leading end portion () of a meniscus structure toward a manifold () and a straight line connecting the leading end part () and a point () located on a profile line of a concave of the meniscus structure, and at a midpoint of a height of the leading end part () from the bottom part () of the concave, which makes it possible to obtain a cell stack device in which the occurrence of cracking at bonded parts between the fuel cells () and the sealing member () is suppressed and reliability is improved.
