Abstract:
1. 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, wherein the sealing portion is provided on a peripheral portion of the separator and on a surface which is the same as the cooling medium channel formation surface, the sealing portion being a seal member in continuous form surrounding only the cooling medium channel and the manifold, wherein the cooling medium regulating portion is formed of a projection provided on the cooling medium channel formation surface side of the separator and inside the continuous sealing portion, wherein the projection is formed of a rib having a fixed-size structure, wherein the sealing portion is outside and along the rib, wherein the cooling medium regulating portion has a height greater than a height of a peripheral portion of the separator and a height of a central portion of the separator, wherein the cooling medium regulating portion isolates the peripheral portion of the separator from the central portion of the separator, and wherein the cooling medium regulating portion is a spacer for stacking the separator with a predetermined spacing.
