    • A fuel cell battery (2) has a structure in which a plurality of cells are stacked and in-series connected. The cells include a cell (15), and one or more cells (16) of a cell stack (11). Hydrogen that has entered the fuel cell battery (2) from a channel (12) is supplied to each cell through a supply manifold (13). After the amount of hydrogen needed for power generation is consumed, gas is discharged as a fuel off-gas into a discharge manifold (14), and then flows into the cell (15). This prevents impurities contained in the fuel off-gas from being accumulated in the cells (16), and causes the impurities to be accumulated in the cell (15). Thus, variations in the amount of power generation among the cells can be restrained in a fuel cell battery system that employs a dead-end method.
    • 燃料电池(2)具有将多个单电池层叠并串联连接而成的结构。 这些单元包括单元(15)和单元堆(11)的一个或多个单元(16)。 已经从通道(12)进入燃料电池(2)的氢通过供应歧管(13)供应到每个电池。 消耗发电所需的氢量后,将气体作为燃料废气排出到排出歧管(14)中,然后流入单元(15)。 这防止了包含在燃料废气中的杂质积聚在电池单元16中,并且导致杂质积聚在电池单元15中。 因此,在采用死端法的燃料电池系统中,可以抑制电池之间发电量的变化。

    • The invention provides a fuel cell, which includes: an electrolyte (23); an anode (22) that is placed on one side of the electrolyte (23) and has a fuel gas consumption surface on which fuel gas is consumed; a cathode (24) that is placed on the other side of the electrolyte (23); and a fuel gas passage (225n) having a first passage (14h) for distributing fuel gas to previously set regions on the fuel gas supply surface, a second passage (22) for supplying the distributed fuel gas to the regions, and a fuel gas supply portion (2In) for supplying fuel gas from the first passage (14h) to the second passage (22). The fuel cell consumes most of the supplied fuel gas in the regions on the fuel gas consumption surface. A fuel gas passage (225n) has a fuel gas leakage suppression portion (14hg, 52n) for suppressing leakage of fuel gas between the first passage (14h) and the second passage (22).
    • 本发明提供了一种燃料电池,其包括:电解质(23); 阳极(22),其被放置在所述电解质(23)的一侧,并且具有消耗燃料气体的燃料气体消耗表面; 放置在电解质(23)的另一侧的阴极(24); 以及燃料气体通路(225n),其具有用于将燃料气体分配到燃料气体供给面上的预先设定区域的第一通路(14h),将分散的燃料气体供给到所述区域的第二通路(22) 用于从第一通道(14h)向第二通道(22)供应燃料气体的供应部分(2In)。 燃料电池在燃料气体消耗表面的区域中消耗大部分供应的燃料气体。 燃料气体通路(225n)具有用于抑制燃料气体在第一通路(14h)与第二通路(22)之间的泄漏的燃料气体泄漏抑制部(14hg,52n)。
