Abstract: 본 발명에 따른 연료전지 스택은, 연료극 전극, 전해질, 및 공기극 전극을 구비하는 전극부; 상기 연료극 전극, 전해질, 및 공기극 전극이 순차적으로 코팅접합되며, 연료가스가 통과하는 금속지지부; 및 상기 공기극 전극이 접하도록 상기 전극부 상에 별도로 배치되며, 공기가스가 통과하는 공기극 집전체;를 포함하는 단위전지가 밀봉재 없이 복수 개가 적층되어, 상기 단위전지들끼리 서로 비부착되어 각각의 상기 단위전지가 개별적으로 교체가능하다.
이와 같이 본 발명은, 전극부와 상기 전극부가 코팅된 평관지지체, 및 공기극 집전체가 하나의 단위전지를 이루도록 구성됨으로써, 단위전지들이 밀봉재 없이도 복수 개가 적층되어 스택구조를 구현할 수 있으며, 나아가 단위전지들이 복수 개 적층 시 양측의 연료가스 매니폴드 사이에서 삽입 및 탈거가 용이하게 이루어짐으로써, 결과적으로 단위전지들끼지 서로 비부착되어 각각의 단위전지가 개별적으로 교체될 수 있다.
이에 따라, 연료전지 스택이 운전 중 이상거동을 하는 경우, 손상된 단위전지만을 탈거하여 새로운 단위전지로 교체할 수 있음으로써, 일부의 손상된 단위전지에 의해 전체 연료전지 스택을 폐기할 필요가 없기 때문에 비용적인 측면에서 효율적인 장점을 지닌다.-

Abstract: The present invention relates to a method for manufacturing a unit cell of a metal-supported solid oxide fuel cell. For the purpose, the present invention provides a method for manufacturing a metal support with a structure in which a plurality of holes are formed selectively in an electrode reaction area except for the edge of a metal powder green sheet laminate, prepared by tape-casting metal powder, and a compact metal foil is formed at the edge portion of the laminate after sintering, such that a cell can be bonded to a separation plate by welding or brazing and holes formed in the middle portion become gas paths to supply fuel gas to an anode layer smoothly. A compact solid electrolyte layer without gas leakage can be prepared by stacking an anode layer and a solid electrolyte layer on the metal support and sintering the anode layer and the solid electrolyte layer simultaneously as the metal support is a metal powder green sheet laminate before sintering while the metal support has the same structure with a selectively perforated metal foil after sintering.
