PURPOSE: A solid oxide fuel cell is provided to prevent fuel gas passing through a gas passage of a non-electrode supporter from leaking to the outside of a formation area of a unit cell. CONSTITUTION: A solid oxide fuel cell includes a non-electrode supporter (11), a fuel electrode barrier (12), a fuel electrode current collector layer (13), a fuel electrode layer (14), an electrolyte film layer (15), an air electrode layer (16), an air electrode current collector layer (17), and a connector (18). The non-electrode supporter is penetrated by a gas passage to the longitudinal direction for passing through fuel. The fuel electrode barrier is installed on the outside of the non-electrode supporter for preventing the reactivity. The fuel electrode current collector layer is installed on the upper side of the fuel electrode barrier. The fuel electrode layer is located on the upper side of the fuel electrode current collector layer, and the electrolyte film layer is located on the upper side of the fuel electrode layer. The air electrode layer is located on the upper side of the electrolyte film layer, and the air electrode current collector layer is located on the upper side of the air electrode layer. The connector is located on the upper side of the fuel electrode barrier, and connects the fuel electrode current collector layer and the air electrode current collector layer. The fuel electrode barrier includes plural gas through-holes connecting the non-electrode supporter and the fuel electrode current collector layer. [Reference numerals] (AA) Air; (BB) Fuel |
