    • The present invention provides a polymer electrolyte fuel cell having a small-sized, light-weighted mechanism for fastening a stack of unit cells assembly. The polymer electrolyte fuel cell of the present invention includes a stack of unit cells obtained by laying a plurality of unit cells one upon another; a first end plate disposed on one end of the stack of unit cells; a second end plate arranged on the other end of the stack of unit cells; an auxiliary plate disposed at least outside the first end plate; at least one set of restraining means, each of which has a band-like shape and restrains a first member located on one end of an assembly, which includes the stack of unit cells, the first and the second end plates, and the auxiliary plate, and a second member located on the other end of the assembly to restrict separation of the first member and the second member from each other; a screw fitted in a threaded hole formed in the auxiliary plate in such a manner that an end of the screw comes into contact with the first end plate; and compressive means that generates a repulsive force to compress the stack of unit cells when the screw is fitted in the threaded hole of the auxiliary plate.
    • 本发明提供一种聚合物电解质燃料电池,其具有用于紧固单电池组件堆叠的小型轻型机构。 本发明的高分子电解质型燃料电池包括将多个单位电池单独放置而得到的单位电池堆叠; 设置在所述单元电池堆的一端的第一端板; 布置在所述单元电池堆的另一端的第二端板; 设置在所述第一端板的至少外侧的辅助板; 至少一组限制装置,每一个限制装置具有带状形状并且限制位于组件一端的第一构件,该第一构件包括单元电池堆,第一和第二端板以及辅助板 以及位于所述组件的另一端的第二构件,以限制所述第一构件和所述第二构件彼此的分离; 安装在形成在辅助板中的螺纹孔中的螺钉,使得螺钉的端部与第一端板接触; 以及当螺钉装配在辅助板的螺纹孔中时产生排斥力以压缩单元电池堆的压缩装置。
