Connecting channel member used in multi-cell type separator for fuel cell and fuel cell stack with the same

Disclosed are: a connecting flow path member detachably attached between a pair of adjacent frames of a multi cell type with a plurality of frames arranged in a line on a plane to guide a fluid to cross an adjacent reaction cell and flow; and a fuel cell stack including the same. The disclosed conne...

Zusammenfassung:	Disclosed are: a connecting flow path member detachably attached between a pair of adjacent frames of a multi cell type with a plurality of frames arranged in a line on a plane to guide a fluid to cross an adjacent reaction cell and flow; and a fuel cell stack including the same. The disclosed connecting flow path member is formed of an elastomer and has a fitting slot formed inwardly so that one end of one frame and one end of another frame of the frames are fitted on the side opposite to the one side, and at least one transverse channel extending to cross the inside is formed so that an opening is formed on one side and the opposite side, and thus, through the transverse channel, the fluid flows from the reaction cell of one frame to the reaction cell of the other frame of the frames. 평면상에 일렬로 배열된 복수의 프레임을 구비한 멀티 셀 타입 분리판의 인접한 한 쌍의 프레임 사이에 탈착 가능하게 부착되어, 유체가 인접한 반응 셀을 가로질러 흐르도록 안내하는 연결 유로 부재, 및 이를 구비한 연료전지 스택이 개시된다. 개시된 연결 유로 부재는, 탄성체(elastomer)로 이루어지고, 일 측면과 반대 측면에 각각 한 쌍의 프레임 중 일 프레임의 단부 및 다른 일 프레임의 단부가 끼워지도록 내측으로 파여진 끼움 슬롯(slot)이 형성되고, 일 측면과 반대 측면에 개구(開口)가 형성되도록 내부를 가로질러 연장된 적어도 하나의 횡단 채널이 형성되어, 횡단 채널을 통하여 유체가 한 쌍의 프레임 중 일 프레임의 반응 셀에서 타 프레임의 반응 셀로 흘러간다.
