Disclosed is a structure of a solid oxide fuel cell, including a porous tubular anode support having a plurality of through holes, and an electrolyte layer and a cathode layer sequentially formed on the inner surface of the tubular anode support, so that fuel flows via the plurality of through holes and air flows through the inside of the cathode layer, thus increasing a diffusion rate of fuel and air to thereby increase the reaction rate, resulting in excellent cell performance. This structure eliminates the flow of fuel and air around the outside of the fuel cell, thus preventing the formation of an oxidizing atmosphere at the inside and outside of the tubular cell, thereby increasing lifespan of the cell and ensuring cell reliability.

Disclosed is a manifold of a fuel cell, including a conductive support having an upper support member and a lower support member between which two or more anode-supported tubular unit fuel cells each comprising an anode layer, an electrolyte layer and a cathode layer formed in sequential order are disposed and which include an inner connector and an outer connector formed to be tightly fitted into an inner surface and around an outer surface of the unit fuel cells so as to electrically conduct the unit fuel cells, such that the unit fuel cells are alternately connected with the inner connector and the outer connector at an upper end and a lower end thereof thus forming an electrical series circuit. The manifold which is essentially manufactured to supply fuel to a solid oxide fuel cell is used to simply collect current from the fuel cell even without an additional current collector being used, and is configured such that unit fuel cells disposed in the manifold are connected in series.

A fuel cell includes a cell unit and a manifold capable of collecting electric current. The cell unit includes a tube support composed of a conductive material, a unit cell laminated on an outer surface of the tube support, and a current collection layer laminated on an outer surface of the unit cell. The manifold includes an inner tube supplying gas into and electrically connected with the tube support, and an outer tube provided outside the inner tube and electrically connected with the current collection layer. By the provision of a current-collectable manifold, a separate metal form or metal wire for current collection is not required.

Disclosed herein is a solid oxide fuel cell, including: one or more unit cells, each being provided with a ceramic tubular support; a metal layer which is formed on an outer circumference of one end of each of the unit cells and collects a first electric current; a metal foam which is formed in each of the unit cells and collects a second electric current; and a manifold which is connected with one end of each of the unit cells to receive the first current collected in the metal layer and which is connected with the other end of each of the unit cells to receive the second current collected in the metal foam. The solid oxide fuel cell is advantageous in that since the metal foam and metal tube are employed, an additional current collector is not required, and the electric current generated from an internal electrode can be easily collected through a manifold by connecting the metal foam and metal tube with the manifold.

Disclosed herein is a tubular solid oxide fuel cell module including an anode layer, an electrolyte layer, a cathode layer divided into two parts or more, a conductive mesh structure and a conductive wire, and a method of manufacturing the same. The tubular solid oxide fuel cell is advantageous in that the cathode is divided into two parts or more, so that the moving distance of electric charges is decreased, with the result that resistance loss can be minimized, thereby increasing the efficiency of collecting electric charges.
