THE SEALING ELEMENT FOR ANODE-SUPPORTED TUBULAR SOLID OXIDE FUEL CELL, AND THE SEALING METHOD OF THE SAME

摘要

Provided is a sealing member for an anode-supported tubular solid oxide fuel cell, which improves the durability and quality of a fuel cell, serves also as a collector for an anode, and allows the production of a fuel cell having a simple structure. The sealing member for sealing both ends of an anode-supported tubular solid oxide fuel cell comprises: a coupling tube(31), which is opened at one end toward the exterior, while being opened at the other end merely through a hole(H) perforated in its central portion in such a manner that the hole is not larger than the sectional area of the gas flow path formed in the inner diameter portion of a fuel cell(2), wherein the coupling tube has an inner space(R) similar to the outer shape of the end of the fuel cell(2) inserted thereto; and a flow path tube(32) extending outwardly from the central portion of the other end of the coupling tube and having a hollow cavity(H') perforated at the central portion along the axial direction, wherein the hollow cavity is extended integrally with the hole(H) of the coupling tube.
