PURPOSE:To easily deform a contact face via fastening and decrease internal resistance by providing a porous intermediate layer between a ribbed substrate supporting a unit cell and a ribbed substrate supporting an inter-connector. CONSTITUTION:A unit cell 17 constituted on an oxidizer electrode 9, a solid electrolyte body 10 and a fuel electrode 11 is laminated on a ribbed substrate 12 made of Zi-ZrO2 cermet, and an intermediate layer 16 made of LaMnO3 with the porosity 80% is provided on it. An inter-connector 13 made of a LaCrO3 and an intermediate layer 15 made of NiO with the porosity 80% are provided on a ribbed substrate 14 made of LaMnO3. The intermediate layer 16 is porous and rib tips of the substrate 14 are acute, thus they are easily collapsed at the time of assembling a battery, contact resistance is decreased, and internal resistance is reduced. |
