Title:
FLAT TUBULAR SOLID OXIDE CELL STACK
Document Type and Number:
WIPO Patent Application WO/2012/015113
Kind Code:
A1
Abstract:
The present invention relates to a flat tubular solid oxide cell stack. In particular, a flat tubular solid oxide cell stack is formed in a stack of a plurality of unit cells (110, 120, and 330), comprising: a first gas flow channel (112) within which a first gas flows formed in a lengthwise direction; a second gas flow channel (113) to the outside of which a second gas flows; and a porous, conductive flat tubular first electrode support (111), wherein connecting holes (114, 124, and 334) are formed in the end of the first gas flow channel and in communication with the first gas flow channel (112) of the adjacent and stacked unit cells, such that the first gas flows in a zigzag pattern along the length of the unit cells. According to this configuration, cell stacking stress is minimized, sealing is performed for a minimal number of sealing portions, and a chemical reaction passage is lengthened such that when the structure is used as a secondary cell, energy generation efficiency is high, and when it is used for steam electrolysis, the purity of emitted gas (hydrogen) is high.
