摘要：
构成本发明的燃料电池(10)的发电单元(12)用第一金属隔板(16)及第二金属隔板(18)夹持电解质膜·电极结构体(14)。第一金属隔板(16)中，在面(16a)上设置有氧化剂气体流路(32)，并且，在面(16b)上设置有冷却介质流路(36)。第一金属隔板(16)具备以波形状成形的金属板(38)，在所述金属板(38)的一侧的面上设置有树脂框构件(40)，并且在所述金属板(38)的另一侧的面上设置有橡胶密封(42)。将金属板(38)、树脂框构件(40)及橡胶密封(42)一体地贯通而形成氧化剂气体入口连通孔(26a)、氧化剂气体出口连通孔(26b)、冷却介质入口连通孔(28a)、冷却介质出口连通孔(28b)、燃料气体入口连通孔(30a)及燃料气体出口连通孔(30b)。
摘要（英）：

A fuel cell according to the present invention includes a power generation cell. The power generation cell is formed by sandwiching a membrane electrode assembly between a first metal separator and a second metal separator. An oxygen-containing gas flow field is formed on one surface of the first metal separator, and a coolant flow field is formed on the other surface of the first metal separator. The first metal separator includes a corrugated metal plate. A resin frame member is provided on one surface of the metal plate, and a rubber seal is provided on the other surface of the metal plate. An oxygen-containing gas supply passage, an oxygen-containing gas discharge passage, a coolant supply passage, a coolant discharge passage, a fuel gas supply passage, and a fuel gas discharge passage extend through the metal plate, the resin frame member, and the rubber seal.
