UNIT CELL OF FLAT-TUBULAR SOLID OXIDE FUEL CELL OR SOLID OXIDE ELECTROLYZER CELL AND FLAT-TUBULAR SOLID OXIDE FUEL CELL AND FLAT-TUBULAR SOLID OXIDE ELECTROLYZER USING THE SAME

摘要

PURPOSE: A flat tubular solid oxide unit cell improves adhesion between unit cells and facilitates the attachment between unit cells. CONSTITUTION: A flat tubular solid unit cell comprises a negative electrode with a first gas flow part which has a plurality of gas flow parts therein; a positive electrode laminated on an electrolyte layer laminated on the negative electrode; a connect member laminated on the opposite side; a connect hole (120) which is formed on the end part of the first gas flow part in a thickness direction; and a sealing part (116) which is outside the connect hole and in which a ring-shaped sealing material (116a) is inserted; and a concave-coupling part (116b) which is wider than the sealing part and is located on the opposite side of the sealing part.
