apparatus for sealing of flat-tubular solid oxide unit cell

摘要

PURPOSE: A sealing device of flat-tubular solid oxide unit cell is provided to minimize the sealing area according to gas flow and physical properties, to remove the difference of cell gaps, and to restraint the flow of sealing material. CONSTITUTION: A sealing device of flat-tubular solid oxide unit comprises: a gas flow channel(112) along longitudinal direction between unit cells which forms a cell stack by stacking each other; a connection hole(114) connecting the gas flow channel by adhering the end of the gas flow channel; a ring shaped sealing groove(116) on the outside of the connection hole; and a sealing ring(150,150'), which is inserted in to the sealing groove, for preventing the leakage of gas through the connection hole.
