-16. (canceled)
A fuel cell comprising a separator having a cooling medium channel in a cooling medium channel formation surface and a manifold formed therethrough to supply a cooling medium to the cooling medium channel, a stacked member stacked on the cooling medium channel formation surface side of the separator, and a sealing portion interposed between the separator and the stacked member to seal the cooling medium flowing in the cooling medium channel,
- wherein a cooling medium regulating portion for regulating the flow of the cooling medium supplied from the manifold to the cooling medium channel formation surface toward a manifold-vicinity portion in the sealing portion placed in the vicinity of the manifold is provided between the manifold-vicinity portion and the manifold while leaving a portion flush with an opening surface of the manifold, a portion of the cooling medium regulating portion and an inner wall of the manifold being flush with each other in the direction of through formation of the manifold.
