    • A cooling system for a fuel cell stack is provided. The fuel cell stack includes electricity generators generating electric energy through an electrochemical reaction between hydrogen and oxygen, and separators between the electricity generators. It may also contain cooling plates between the electricity generators. Cooling channels including main channels and branch channels coupling the main channels together are formed in the separators or the cooling plates. The intersection of the main and branch cooling channels forms grid-shaped areas with pillars in between that are rectangular, triangular, circular, shaped like a parallelogram, or formed in a combination of these shapes. The cooling channels increase the contact area between the coolant and the separators or the cooling plates and therefore the cooling efficiency of a stack.
    • 提供了一种用于燃料电池堆的冷却系统。 燃料电池堆包括通过氢和氧之间的电化学反应产生电能的发电机和发电机之间的分离器。 它也可能包含发电机之间的冷却板。 在分离器或冷却板中形成包括主通道和主通道连接在一起的分支通道的冷却通道。 主分支冷却通道的交点形成具有矩形,三角形,圆形,类似平行四边形形状的柱状的网格形区域,或者形成为这些形状的组合。 冷却通道增加了冷却剂与分离器或冷却板之间的接触面积,从而增加了堆叠的冷却效率。
