    • In a fuel cell having a cell structure in which a gas flow passage is formed by an expanded metal, a bond portion connecting a mesh of the expanded metal stands partially upright in a position where a bond length is shortened so as to form a part of a strand portion. Hence, in an opening formed by the mesh of the expanded metal, a surface area on which front and rear openings overlap in a direction increases when seen from an direction. Thus, a sectional area of gas flow passages constituted by a continuum in the direction of the openings overlapping in the direction increases. As a result, a gas flow flows without making repeated narrow turns, leading to a reduction in gas pressure loss.
    • 在具有通过膨胀金属形成气体流路的电池结构的燃料电池中,将金属制金属支架的网状部分直立连接在键长缩短的位置的结合部分,以形成 股线部分。 因此,在由多孔金属网形成的开口中,从方向观察时,前后开口重合的表面积增加。 因此,由开口方向上的连续体构成的气体流路的截面面积增大。 结果,气体流动而不会产生重复的匝数,导致气体压力损失的降低。

    • A fuel cell comprises a membrane electrode assembly including an electrolyte membrane and electrode layers arranged on each surface of the electrolyte membrane respectively, and first and second separators that are formed by processing a metal plate and are arranged so as to sandwich the membrane electrode assembly. At a position outside a position facing the membrane electrode assembly, the separators have an opening that constitutes a reaction gas flow path that is roughly perpendicular to a surface direction of the membrane electrode assembly. The first separator has a folded back part that is formed by folding back at least part of the metal plate of the position at which the opening is formed toward the membrane electrode assembly side along a boundary line on the membrane electrode assembly side of the opening as a fold line. The folded back part has a communication hole that allows communication between an internal flow path space and the reaction gas flow path, the internal flow path space being a space communicated with an end surface of the membrane electrode assembly and being formed between the folded back part and the first separator. The second separator does not have the folded back part.
    • 燃料电池包括分别包括电解质膜和布置在电解质膜的每个表面上的电极层的膜电极组件,以及通过加工金属板形成并且被布置成夹住膜电极组件的第一和第二隔板。 在面向膜电极组件的位置之外的位置处,分离器具有构成大致垂直于膜电极组件的表面方向的反应气体流动路径的开口。 第一分离器具有折回部,其通过沿着开口的膜电极组件侧的边界线向开口形成开口的位置的至少一部分的膜电极组件侧折回而形成, 折线。 折回部具有能够使内部流路空间与反应气体流路连通的连通孔,内部流路空间与膜电极接合体的端面连通并形成在折回部之间 和第一分离器。 第二分离器没有折回部分。
