燃料电池
摘要：
本发明提供一种燃料电池。构成燃料电池的电池单元(12)具备第二隔板(18)。在第二隔板(18)的面(18a)上形成有第一氧化剂气体流路(50)，入口缓冲部(52)及出口缓冲部(54)与所述第一氧化剂气体流路(50)的入口及出口连通。入口缓冲部(52)具有第二入口缓冲区域(52b)和槽深的第一入口缓冲区域(52a)，而出口缓冲部(54)具有第二出口缓冲区域(54b)和槽深的第一出口缓冲区域(54a)。第一入口缓冲区域(52a)和第一出口缓冲区域(54a)相互设定成不同的表面积。
摘要（英）：

A cell unit of a fuel cell includes a second separator. A first oxygen-containing gas flow field is formed on a surface of the second separator. An inlet buffer is connected to an inlet of the oxygen-containing gas flow field, and an outlet buffer is connected to an outlet of the first oxygen-containing gas flow field. The inlet buffer includes a first inlet buffer area having a deep groove and a second inlet buffer area, and the outlet buffer includes a first outlet buffer area having a deep groove and a second outlet buffer area. The first inlet buffer area and the first outlet buffer area have different surface areas.
