STACK OF SOLID OXIDE FUEL CELL

摘要

PURPOSE: A solid oxide fuel cell stack is provided to improve rigidity and durability stably coupling and laminating cells by a surface contact between unit cells. CONSTITUTION: A solid oxide fuel cell(1) in which a plurality of unit cells(100) are laminated comprises an electrode which includes an air electrode and a fuel electrode disposed in a diameter direction; electrolyte inserted between the air electrode and fuel electrode; and at least one reinforcing part(70) which reinforces rigidity and is protruded from one electrode toward outside. The unit cells are surface contacted to each other by the reinforcing part.
