TUBULAR SOLID OXIDE FUEL CELL WITH EXTERNAL CURRENT COLLECTION AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A tubular solid oxide fuel cell is provided to facilitate series connection of a solid oxide fuel cell, and to have uniform fuel flux by not inserting a current collector, thereby obtaining uniform and excellent performance. CONSTITUTION: A tubular solid oxide fuel cell(100) comprises a cylindrical fuel electrode support; an electrolyte layer(130) formed on the outer side of the cylindrical fuel cell support; and an air electrode(120) formed on the electrolyte layer; a current collector(110) which includes silver-glass paste coating layer formed on the surface of the inlet and the outlet of the cylindrical fuel electrode support and a metal-mesh and conductive metal-wire winded around the coating layer. The conducive metal is one or a mixture of two or more selected from Ag, Au, Pt, Ni, Co, W, Ti, Cu, Pd, Mn, Mo, and Si.
