Giant stack for flat tube type solid oxide fuel cell and method for producing the same

摘要

The present invention relates to a stack for a solid oxide fuel cell and a manufacturing method thereof, and more specifically, to a stack for a high-capacity solid oxide fuel cell and a manufacturing method thereof, in which cell modules comprising a flat-tubular reformer integrated with flat-tubular reactors are electrically connected to form a cell bundle. In a cell module of the stack for the solid oxide fuel cell according to the invention, at least one flat-tubular reactor is stacked on a flat-tubular reformer, wherein the flat-tubular reformer is closed at one side and has formed therein at least one first channel extending to the outside; the flat-tubular reactor is closed at one side and has formed therein at least one second channel extending to the outside; reaction units and air channels are formed on the outside of the flat-tubular reactor; and the first channel and the second channel communicate with each other. A plurality of the cell modules are stacked to form a cell bundle, and a plurality of the cell bundles are electrically in series and in parallel to form a cell stack. Thus, the invention enables a stable reaction by producing high-capacity electricity, and obtains stability in long-term operation due to easy replacement.
