Abstract

본 발명은 고체산화물 연료전지용 스택 및 그 제작 방법에 관한 것으로서, 보다 상세하게는 직병렬 구조로 전기를 생산할 수 있는 고체 산화물 연료전지용 스택 및 그 제작 방법에 관한 것이다. 본 발명에 따른 고체산화물 연료전지용 스택은 평관형 지지체의 전단면 및 외부면 일측에 제1전극과 연결된 제1전기연결재가 형성되고, 후단면 및 외부면 일측에 제2전극과 연결된 제2전기연결재가 형성된 단위 셀모듈을 제조하고, 상기 셀모듈의 외측면의 같은 극 끼리 연접되도록 적층하여 전기적으로 병렬연결된 단위 스택모듈을 제조하고, 상기 스택모듈의 전후면을 직렬 연결하여 직병렬 혼합식 고체산화물 연료전지용 일체형 (monolithic) 스택을 제조하는 것을 특징으로 한다. 본 발명에 따른 고체산화물 연료전지용 스택은 고체산화물 연료전지용 스택의 제작 방법에 있어서 가장 약점으로 지적되는 단위 셀들의 대면적화의 어려움, 직렬연결에만 의존한 스택 성능의 단위셀에 의한 직접적인 의존성, 적층에 의한 대형 스택의 제작의 어려움 등을 해결할 수 있다.
