PURPOSE: A solid oxide fuel cell is provided to facilitate the installation of a current collector, by improving the structure of the current collector of a unit cell, and to improve current collecting efficiency. CONSTITUTION: A solid oxide fuel cell comprises a fuel cell unit cell(100) having a multi-tubular structure, which is the structure of a first electrode, an electrolyte layer, and a second electrode are laminated in order. The multi-tubular structure comprises a first current collector which is connected to the one end part of the unit cell; a second current collector which is connected to the other end of the unit cell. Among the first and the second current collector, at least one collector is formed on one or more surface among the end surface of the unit cell, the inner peripheral surface of the unit cell, and the outer peripheral surface. The current collector comprises a cover part in the inlet of the unit cell, and an internal current collecting part(214), which is expanded from the surface of a cover part facing the unit cell, inserted into the inner peripheral surface of the unit cell. |
