PURPOSE:To prevent a gas including oxygen or a fuel gas from leakage to the outside and to reduce a cost by providing a heat insulating body surrounding a cell accumulated body. CONSTITUTION:A heat insulating material 32 is arranged so as to surround a cell accumulated body U, in which plural cells C are parallelly layered. In the heat insulating material 32, a clearance part 33, which communicates with a penetrating hole 31C formed in a bottom part 3lB of a box body 31, is arranged. A fuel gas supply pipe 34 is communicably connected to the penetrating hole 31C. A gas including oxygen gas is supplied to an oxygen including gas passage S in each cells C via an external oxygen gas including gas supply pipe 36 and an internal oxygen gas including gas supply pipe 35, while a fuel gas F is supplied to a fuel gas passage in each cells C via the fuel gas supply pipe 34 and a fuel gas supply part Kf. In this way, power is generated in a cell layered part NC by the oxygen including gas and the fuel gas. Therefore, the heat insulating material 32 suppresses transmission of heat in the cell accumulated body to the box body 31, and a temperature rise in the box body can be suppressed, so that an inexpensive metal can be used. |
