Abstract
A cell stack device may include a cell stack of connected cells, a manifold configured to fix lower ends of the cells and supply a reaction gas into gas flow passages of the cells, and a reaction gas supply pipe connected to the manifold and configured to supply the reaction gas to the manifold. The manifold may include an insertion portion connecting the reaction gas supply pipe to the manifold, and a gap between the insertion portion and the reaction gas supply pipe. The manifold may further include a first joining portion joining the insertion portion and the reaction gas supply pipe and configured to seal an end of the gap. In a cross-section along an insertion direction of the reaction gas supply pipe, the first joining portion may have a meniscus shape, and a joint length is longer than a thickness of the reaction gas supply pipe.
