摘要： A method of manufacturing a unit cell of a solid oxide fuel cell using a transfer process, in which an anode, electrolyte, cathode and interconnect are deposited on a substrate using the transfer process when the unit cell of the solid oxide fuel cell having a variety of shapes, such as a planar type, a horizontal pipe type, a tubular type, a segmented type, and the like, is manufactured. In manufacture of solid oxide fuel cells having a variety of shapes according to lamination and arrangement of unit cells, the components of each unit cell, such as the anode, the cathode, the electrolyte, the interconnect, and the like, may be deposited in a desired shape using the transfer process through deposition or coating, so that the components of the unit cell having a large scale or a complicated structure can be deposited without limit in size and shape, the thickness of the components of the unit cell can be easily controlled depending on the number of stacked transfer paper sheets, and a coating film can be formed on a substrate at a lower cost.
