摘要： A fuel cell stack structure includes, for example, a plurality of unit cells each having an aperture formed therethrough. A first fuel cell stack is formed by stacking the plurality of unit cells in a stacking direction and has an internal manifold opening defined by the apertures. A fluid passage within the cell for flowing a fluid that flows within the internal manifold is configured and arranged to flow the fluid in a plane generally perpendicular to the stacking direction of the unit cell. The structure also includes an external manifold having an external passage for supplying the fluid to the internal manifold, wherein the fluid flowing within the external passage creates a vortex proximal to the internal manifold by an external manifold surface facing a flow direction of the fluid.
