Abstract

A cell assembly is formed by stacking a first cell and a second cell. In the cell assembly, oxygen-containing gas flow passages are connected in series by an intermediate oxygen-containing gas flow passage, and fuel gas flow passages are connected in series by an intermediate fuel gas flow passage. An additional oxygen-containing gas is supplied to an oxygen-containing gas passage which includes the intermediate oxygen-containing gas flow passage. An additional fuel gas is supplied to a fuel gas passage which includes the intermediate fuel gas flow passage.
