SOLID OXIDE FUEL CELL AND FUEL CELL STACK

摘要

A solid oxide fuel cell and a fuel cell stack are disclosed. The fuel cell stack may include a current collector electrically connected to inner and outer circumferential surfaces of a unit cell and a cap structure. The connection process between the current collector and the unit cell may be easily performed. As an external current collecting portion may be formed to surround the outer circumferential surface of the unit cell. Unit cells may be coupled to manifolds and electrically connected to one another.
