Abstract
A cell stack device includes a manifold, a fuel cell, and an oxygen-containing-gas ejection portion. The manifold includes a fuel gas supply chamber and a fuel gas collection chamber. The fuel cell extends upward from the manifold. The oxygen-containing-gas ejection portion is disposed upward of the center of the fuel cell. The oxygen-containing-gas ejection portion ejects oxygen-containing gas toward the fuel cell. A support substrate of the fuel cell includes a first gas channel and a second gas channel. The first gas channel is connected to a fuel gas supply chamber, and the second gas channel is connected to the fuel gas collection chamber. The first gas channel and the second gas channel are connected to each other in an upper end portion of the fuel cell.
