PURPOSE: A solid oxide fuel cell is provided to increase output performance of stack by preventing conductance between an air electrode and a fuel electrode and to extend lifetime of the stack. CONSTITUTION: A solid oxide fuel cell(100) comprises unit cells(10) which includes an electrolyte film(11), an air electrode(12) and a fuel anode(13), frames(20) which is fixed to edge of the unit cell by a joint layer(41) and includes the joint layer(41) and a cutting part(23), a first separator(31) located in the outside of the frame and the air electrode, a second separator(32) located in the outside of the frame and the fuel anode, and an insulating layer(51) which prevents electricity communication of the fuel anode and the air electrode frame. |
