UNIT STACK OF SOLID OXIDE FUEL CELL

摘要

PURPOSE: A unit stack of a solid oxide fuel cell is provided to ensure excellent durability while being not collapsed in an operation temperature despite long-term operation since a sealing material module is made of materials with endurance at the temperature of each region of the unit stack. CONSTITUTION: A unit stack of a solid oxide fuel cell comprises a plurality of unit battery cells(601,602). The unit battery cell includes a unit cell, a connector connected to the neighboring unit battery cell, and a sealing material module, wherein the sealing material module comprises a supporter installed at the upper and lower parts of the unit battery, and at least one of a sealing sheet or sealing paste adhered to the upper and lower parts of the supporter. The supporter or sealing material module is respectively made of different materials at the lower part(606) of the stack and the upper part(605) of the stack.
