STACK FOR A SOLID OXIDE FUEL CELL USING A FLAT TUBULAR STRUCTURE

摘要

The present invention relates to a stack for a solid oxide fuel cell and to a method for producing same, and more particularly, to a stack for a solid oxide fuel cell capable of generating electricity in a serial and parallel structure. The stack for a solid oxide fuel cell according to the present invention is produced by the steps of: producing a unit cell module in which a flat tubular support structure has a first electrical connector formed on the front surface and on the outer surface thereof and connected to a first electrode, and has a second electrical connector formed on the rear surface and on the outer surface thereof and connected to a second electrode; stacking the unit cell modules such that same poles at the outer surfaces of the unit cell modules contact each other, to produce a unit stack module in which the unit cell modules are electrically connected together in parallel; and connecting the front and rear surfaces of the unit stack modules together in series, thereby producing a combined serial- and parallel-type monolithic stack for a solid oxide fuel cell. The stack for a solid oxide fuel cell according to the present invention solves the most serious problems in producing stacks for a solid oxide fuel cell, such as difficulties in producing large-scale unit cells, the direct dependence on unit cells connected in series in determining the performance of the stack, and difficulties in producing large-scale stacks by stacking unit cells.
