    • A solid oxide fuel cell stack is provided in which a separate fuel-blocking unit is provided to each fuel supply tube that connects a fuel supply unit to each bundle portion of the stack, so that the fuel supply to a defective bundle portion may be selectively blocked, thereby preventing the risk of explosion due to fuel leakage and the performance degradation of the other bundle portions. To this end, a fuel cell stack includes a bundle portion including unit cells each having a stacked structure of a first electrode, an electrolytic layer, and a second electrode, and a manifold having the unit cells connected thereto. A fuel supply portion is connected to the manifold of the bundle portion through a fuel supply tube provided at one side thereof. A fuel-blocking unit is connected to the fuel supply tube to block the fuel supply tube.
    • 提供了一种固体氧化物燃料电池堆,其中,将燃料供给单元连接到堆叠的每个束部的每个燃料供给管设置有单独的燃料阻断单元,从而可以选择性地向缺陷束部分供应燃料 从而防止燃料泄漏引起的爆炸危险和其他束部的性能下降。 为此,燃料电池堆包括包括单元电池的束部,每个单元具有第一电极,电解质层和第二电极的堆叠结构,以及具有与其连接的单元电池的歧管。 燃料供给部通过设置在其一侧的燃料供给管连接到束部的歧管。 燃料阻断单元连接到燃料供应管以阻挡燃料供应管。

    • Disclosed is a fuel cell system, which bypasses a cell, bundle, or stack. The fuel cell system includes a stack, which includes at least one unit cell including an anode, a cathode, and an electrolyte formed between the anode and the cathode. The unit cell produces electricity via an electrochemical reaction of hydrogen and oxygen provided from the anode and the cathode. The fuel cell system includes switches connected in series for connecting the unit cells in series or for short-circuiting one unit cell with adjacent unit cells, and a bypass switch to connect two unit cells separated by at least one unit cell. The fuel cell system reduces or minimizes influence of a defective cell, bundle, or stack on another normal cell, bundle, or stack, and thus the fuel cell system may operate for a long time and have excellent durability.
    • 公开了一种旁路电池,束或堆的燃料电池系统。 燃料电池系统包括堆叠,其包括至少一个单元电池,其包括阳极,阴极和形成在阳极和阴极之间的电解质。 单元电池通过从阳极和阴极提供的氢和氧的电化学反应产生电。 燃料电池系统包括串联连接的开关,用于串联连接单元电池或将一个单元电池与相邻单元电池短路;以及旁路开关,用于连接由至少一个单元电池隔开的两个单元电池。 燃料电池系统减少或最小化有缺陷的电池,束或堆叠对另一个正常电池,电池组或堆叠的影响,因此燃料电池系统可以长时间运行并且具有优异的耐久性。
