Abstract: 본 발명은 원자막 증착법으로 형성된 이트리아-안정화 지르코니아 기능층을 포함하는 세리아계 전해질 및 이를 포함하는 고체 산화물 연료전지에 관한 것이다. 본 발명의 여러 구현예에 따라 형성된 전해질 기능층은 하기와 같은 여러 효과를 보일 수 있음을 확인하였다. 즉, 환원 기체로부터 세리아가 보호되고, 전자 인슐레이션을 얻을 수 있으며, 상대적으로 산소이온의 저항이 큰 YSZ막을 얇게 증착시킴으로써 저항 손실을 최소화할 수 있을 뿐만 아니라, 기능층의 두께 조절이 용이하고, 형성된 막의 밀도에서의 차이가 거의 없어 환원 기체에의 노출에 상대적으로 강하다. 또한, 서브-nm의 박막을 증착할 수 있고, 대면적 증착이 가능하며, 증착 균일도와 스텝 커버리지(step coverage)가 우수하고, 다성분 필름 증착이 가능하며, 높은 증착 밀도 및 핀홀이 없는 층의 증착이 가능하다는 장점이 있다.
