    • A compression assembly for distributing an external compression force to a solid oxide fuel cell stack, the compression assembly comprising a force distributing plate, and a force distributing layer so that when said compression assembly is mounted together with the solid oxide fuel cell stack, the external compression force is exerted on the force distributing plate and the force distributing layer is provided next to a surface of at least one end plate, opposite to the surface facing the solid oxide fuel cells. The force distributing layer has a rigid frame extending next to a region of a sealing area of the solid oxide fuel cell stack. One or more resilient elements are placed inside the space enclosed by the rigid frame and positioned next to an electrochemically active area of the solid oxide fuel cell stack, so that when the compression assembly mounted with the solid oxide fuel cell is in use, the force distributing layer provides an unequally pressure distribution across the region of the sealing area and the electrochemically active area.
    • 一种用于将外部压缩力分配到固体氧化物燃料电池堆的压缩组件,所述压缩组件包括力分配板和力分布层,使得当所述压缩组件与固体氧化物燃料电池堆一起安装时,外部 压力施加在力分布板上,并且力分配层设置在与面向固体氧化物燃料电池的表面相对的至少一个端板的表面旁边。 力分布层具有紧邻固体氧化物燃料电池堆的密封区域的区域延伸的刚性框架。 将一个或多个弹性元件放置在由刚性框架包围的空间内部并且位于固体氧化物燃料电池堆的电化学活性区域旁边,使得当安装有固体氧化物燃料电池的压缩组件被使用时, 分布层在密封区域和电化学活性区域的区域上提供不均匀的压力分布。
