The interior of a manifold ( 1 ) comprises, for each of a plurality of fluid types supplied to a fuel cell stack ( 2 ), an interior side passage ( 11 b- 13 b) connected to a fluid supply/discharge port ( 2 f) of the stack, and an exterior side passage ( 11 a- 13 a) which connects the interior side passage to an external pipe. The interior side passage is formed in tiered fashion for each of the fluid types, and one or all of the exterior side passages and interior side passages communicate via a volume portion ( 11 c- 13 c) which passes vertically through the interior of the manifold in the tier direction. By providing the volume portion, which has a large passage sectional area, resistance acting on the fluid that flows into the stack can be reduced, and as a result, energy loss can be suppressed. |
