MICRO CYLINDRICAL SOLID OXIDE FUEL CELL STACK AND SOLID OXIDE FUEL CELL POWER GENERATION SYSTEM COMPRISING THE SAME

摘要

PURPOSE: A micro cylindrical solid oxide fuel cell stack is provided to have high power density through a direct connection of unit cells, and to be able to have light weight and to minimize heat loss by optimizing arranging structure of a fuel cell chamber, an air electrode chamber and unit cells. CONSTITUTION: A micro cylindrical solid oxide fuel cell stack(100) comprises: a plurality of cylindrical solid oxide fuel cell(10); a fuel electrode chamber(20) comprising a fixation part fixing the solid oxide fuel cell and a fuel electrode chamber comprising a fuel injection pipe supplying fuel into the solid oxide fuel cell; an air electrode chamber(30) comprising an air electrode tube(31) in which the solid oxide fuel cell is inserted, an air supply part surrounding an outside of the solid oxide fuel cell; and an air injection pipe supplying air into the air supply part. The air electrode chamber inserts a fuel cell into an air electrode tube, and is sealed by combining with the fuel electrode chamber.
