    Abstract: 본 발명은 연료전지 스택에 반응 기체인 수소 및 공기(산소)를 공급할 때, 전기화학 반응의 생성물인 물이 영하 조건에서 결빙하는 것을 감소시키기 위해 연료전지 셀 내 접촉저항을 감소시킬 수 있도록 설계된 연료전지용 스택에 관한 것이다.
    즉, 본 발명은 기존 스택 생산 공정에 대한 추가적인 공정 개질없이 그대로 이용하되, 단지 연료전지 셀에 적합한 시트(Sheet) 크기로 기체확산층을 재단(Cutting)하는 방식만을 최적화시켜 제조되는 기체확산층, 즉 기체확산층의 분리판 채널로의 침투를 최소화하기 위해 기체확산층 롤 원단 고유의 고강성 기계방향과 분리판 주 유로 방향이 서로 평행하지 않도록 재단하여 주 유로를 가로지르는 횡 방향의 기체확산층 강성을 증가시킨 기체확산층을 적용하여, 연료전지 셀 내 접촉 저항을 감소시키고 냉해동 내구성을 향상시킬 수 있도록 한 냉해동 내구성이 우수한 연료전지용 스택을 제공하고자 한 것이다.
