PURPOSE:To prevent the warping of a unit cell, prevent the mixed contact of reaction gas, and facilitate manufacture by laminating a substrate laminatingly supporting a unit cell and a substrate supporting an inter-connector in turn. CONSTITUTION:A porous substrate 2 and a dense substrate 3 are formed with NiO and ZrO2. A unit cell 30 constituted of a fuel electrode 5, a solid electrolyte body 6 and an oxidizer electrode 7 is formed on one of main faces of a substrate 31B, and a guide blade 32 feeding H2 gas is provided on the other face of the substrate 31B. An oxidizer gas feed hole 9 and a fuel gas feed hole 10 are provided on the substrate 3, and a fine hole 11 communicate from the hole 10 to the substrate 2 is provided. A gas sealing glass ring groove 12 is provided around the hole 9. A unit cell plate is manufactured as follows: ZrO2 powder is mixed with NiO, it is press-molded into a disk, which is sintered to obtain the substrate 3. The substrate 3 thus obtained is crushed into powder. A dense disk is placed at the center of a disk-shaped die, the crushed powder is filled on the periphery, then it is press-molded and sintered to obtain the substrate 31B. The fuel electrode 5, electrolyte body 6 and oxidizer electrode 7 are welded by plasma-flame spraying. |
