    • There is provided a coolant manifold that is installed to a fuel cell stack so as to distribute coolant through the fuel cell stack, which is constituted by stacking a plurality of unit cells and has more than one communication holes for coolant supply and at least one communication hole for coolant discharge, in which the coolant flows in an order from the communication holes for coolant supply through a plurality of the unit cells to the communication hole for coolant discharge. The coolant manifold includes a manifold body having a manifold chamber that extends along an alignment direction of the communication holes for coolant supply, and an external communication part having an external communication hole for communicating the manifold chamber with external. A center axis of the external communication hole is placed unparallel and non-vertical relative to a center axis of each communication hole for coolant supply.

    • A fuel cell stack having stacked unit fuel cells, each having a pair of separators between which a membrane electrode assembly is provided, which includes an anode and a cathode. Each separator has protruding lines arranged vertically in a zigzag manner, which protrude in a direction going away from the membrane electrode assembly. A space between the anode and the protruding lines of the separator facing the anode is used as a fuel gas passage. A space between the cathode and the protruding lines of the separator facing the cathode is used as an oxidant gas passage. At least part of the separators are each arranged in close contact with another separator so that a coolant passage through which a coolant flows horizontally is formed between both separators. A lower area of the coolant passage has a larger flow resistance than that of an upper area thereof.
    • 一种具有堆叠单元燃料电池的燃料电池堆,每个燃料电池具有一对隔板,在该隔板之间设置有包括阳极和阴极的膜电极组件。 每个分离器具有以锯齿形方式垂直布置的突出线,其沿远离膜电极组件的方向突出。 阳极与面向阳极的隔膜的突出线之间的空间用作燃料气体通道。 阴极与分离器面对阴极的突出线之间的空间用作氧化剂气体通道。 分离器的至少一部分各自布置成与另一个分离器紧密接触,使得在两个分离器之间形成冷却剂水平流过的冷却剂通道。 冷却剂通道的下部区域的流动阻力比其上部区域的流动阻力大。
