Zusammenfassung:To provide a separator for a fuel cell including a guide pattern capable of enhancing efficiency of a fuel cell, and a fuel cell stack including the separator.SOLUTION: A separator 20 for a fuel cell is provided, including a central part with a rectangular shape, and a surrounding part disposed to surround the central part. The surrounding part 23 includes an outlet manifold 130 positioned at one of pairs of edges of the central part 21, which oppose each other, and an inlet manifold 110 positioned along a side of the central part and provided to be adjacent to another edge except for the pair of edges at which the outlet manifold is positioned, and the central part includes a plurality of guide patterns 200 that are spaced apart from each other to guide fluids introduced through the inlet manifold so as to flow toward the outlet manifold.SELECTED DRAWING: Figure 3 【課題】燃料電池の効率を上昇させることができるガイドパターンを含む燃料電池用分離板及びこれを含む燃料電池スタックを提供する。【解決手段】四角形の中心部及び前記中心部を取り囲むように配置される周辺部を含む燃料電池用分離板20であって、前記周辺部23は、前記中心部21の互いに対向するいずれか一対の角部側に位置する排出マニホールド130、及び前記中心部の辺に沿って位置し、前記排出マニホールドが位置する一対の角部を除いた他の角部に隣接するように提供される流入マニホールド110を含み、前記中心部は、前記流入マニホールドを介して流入する流体が前記排出マニホールドに向かって流動するようにガイドする互いに離隔した複数のガイドパターン200を含む。【選択図】図3
