    • PURPOSE: A fuel cell stack is provided to reduce the volume of fuel cell system, reduce manufacturing cost, and minimizing the number of component by not including additional humidifier. CONSTITUTION: A fuel cell stack comprises a film-electrode assembly(10), a separator(20), a first end plate(41), and a second end plate(42). The separator located between membrane-electrode assemblies, supplies fuel and oxidant to the membrane-electrode assemblies. The first and the second end plates are in the outside of the outermost separator. The first end plate forms an oxidant inlet(61), an oxidant outlet(62), and moisture flow paths(70), the moisture flow path connects the oxidant inlet and the oxidant outlet. The moisture flow path comprises a first end contacting with the oxidant outlet, and a second end contacting with the oxidant inlet. The first end is larger and higher than the second end. The first end locates parallel to ground. Two moisture flow paths are formed, of which size are different from each other, along the length direction. The moisture flow paths comprises a first path of which size is same with the first end, and a second flow path of which size is same with the second end.
    • 目的:提供燃料电池堆,以减少燃料电池系统的体积,降低制造成本,并通过不包括额外的加湿器来最小化部件数量。 构成:燃料电池堆包括膜 - 电极组件(10),隔板(20),第一端板(41)和第二端板(42)。 位于膜 - 电极组件之间的隔膜将膜和电极组件供给燃料和氧化剂。 第一和第二端板位于最外侧隔板的外侧。 第一端板形成氧化剂入口(61),氧化剂出口(62)和湿气流动路径(70),湿气流动路径连接氧化剂入口和氧化剂出口。 水分流路包括与氧化剂出口接触的第一端和与氧化剂入口接触的第二端。 第一端大于第二端。 第一端与地平行。 沿着长度方向形成两个湿度流动路径,其尺寸彼此不同。 湿气流路包括与第一端大小相同的第一路径和与第二端尺寸相同的第二流路。
