Disclosed is a support for a solid oxide fuel cell, which is easily manufactured, enables scale-up, facilitates gas sealing and has a drastically increased reaction area, a monolith type unit cell using the support, and manufacturing methods thereof. In the unit cell for the fuel cell, first gas channels are formed in a porous flat tube type support made of a conductive material, and a plurality of protrusions formed on upper and lower outer surfaces thereof forms second gas channels upon stacking of unit cells, thus simultaneously producing current on both the upper and lower outer surfaces of the support. On the lower surface of the unit cell, a first electrode layer, an electrolyte layer, and a second layer are sequentially formed, whereas a first electrode layer is formed on the upper surface of the unit cell, an electrolyte layer and an interconnection layer are respectively formed on recesses and protrusions thereof, and a second electrode layer is formed on recesses so as not to come into contact with the interconnection layer. Also provided are methods of manufacturing a support and a monolith type unit cell for a solid oxide fuel cell, which are structurally stable, enable scale-up, and have no gas sealing problems and an effective reaction area increased up to 300 % compared to an apparent stack area, thus drastically improving cell performance. |
