Claims (10)
- 복수의 연료 전지의 적층체(1)의 내측에 적층 방향으로 형성된 내부 매니폴드(16)와, 내부 매니폴드(16)에 유체를 공급하는 외부 유체 통로(22)를 구비하고, 각 연료 전지가 내부 매니폴드(16)에 직교 방향으로부터 접속되는 셀 내 유체 통로(15)를 구비하고, 외부 유체 통로(22)는 내부 매니폴드(16)의 일단부에 직교 방향으로부터 접속되는 연료 전지 스택의 유체 통로 구조에 있어서,외부 유체 통로(22)로부터 내부 매니폴드(16)로 유입하는 유체의 에너지를 이용하여, 내부 매니폴드(16) 내에 선회류를 발생시키도록 외부 유체 통로(22)를 내부 매니폴드(16)에 접속하는 접속부(16a)를 구비한 것을 특징으로 하는 연료 전지 스택의 유체 통로 구조.
- 제1항에 있어서, 접속부(16a)는 내부 매니폴드(16)의 벽면으로부터의 유체의 박리를 저지하도록 구성되는 연료 전지 스택의 유체 통로 구조.
- 제1항에 있어서, 접속부(16a)는 내부 매니폴드(16) 내의 유체의 흐름에 역순환 현상이 일어나는 것을 저지하도록 구성되는 연료 전지 스택의 유체 통로 구조.
- 제1항에 있어서, 접속부(16a)는 내부 매니폴드(16)의 유체의 흐름에, 내부 매니폴드(16)의 횡단 방향의 속도 성분을 갖게 하도록 구성되는 연료 전지 스택의 유체 통로 구조.
- 제1항 내지 제4항 중 어느 한 항에 있어서, 접속부(16a)는 셀 내 유체 통로(15)의 형성 방향과 외부 유체 통로가 내부 매니폴드의 중심축 방향으로부터 본 상태에서 0도보다 크고 90도보다 작은 교차각을 이루도록, 외부 유체 통로(22)를 내부 매니폴드(16)에 접속하도록 구성되는 연료 전지 스택의 유체 통로 구조.
- 제1항 내지 제4항 중 어느 한 항에 있어서, 접속부(16a)는 내부 매니폴드(16)의 횡단면의 중심선으로부터 오프셋한 위치에서, 외부 유체 통로를 내부 매니폴드에 접속하도록 구성되는 연료 전지 스택의 유체 통로 구조.
- 제1항 내지 제4항 중 어느 한 항에 있어서, 내부 매니폴드(16)의 횡단면은 가로로 긴 직사각형 단면으로 형성되는 연료 전지 스택의 유체 통로 구조.
- 제1항 내지 제4항 중 어느 한 항에 있어서, 내부 매니폴드(16)의 횡단면은 세로로 긴 직사각형 단면으로 형성되는 연료 전지 스택의 유체 통로 구조.
- 제1항 내지 제4항 중 어느 한 항에 있어서, 접속부(16a)는 내부 매니폴드(16) 내에 방향이 다른 2개의 선회류를 형성하도록 구성되는 연료 전지 스택의 유체 통로 구조.
- 제1항 내지 제4항 중 어느 한 항에 있어서, 연료 전지 스택은 복수의 적층체(1)와, 복수의 적층체(1)의 외측에 형성된 외부 매니폴드(4A, 4B)를 구비하고, 외부 유체 통로(22)는 외부 매니폴드(4A, 4B) 내에 형성된 유체의 저류 스페이스(21)와 각 적층체의 내부 매니폴드(16)를 접속하는, 외부 매니폴드(4A, 4B) 내에 형성된 분기 통로로 구성되는 연료 전지 스택의 유체 통로 구조.
