    • A fuel cell stack is provided comprising one or more fuel cell modules, each fuel cell module comprising at least one membrane electrode assembly having no hard stop layer; two or more compression plates; and at least one plurality of mechanical linkages connecting a pair of compression plates located on either side of at least one fuel cell module, which may be engaged to maintain a predetermined gap distance between the pair of compression plates. The present invention additionally provides a fuel cell stack comprising: two or more fuel cell modules stacked alternately with three or more compression plates; a first plurality of mechanical linkages connecting a first pair of compression plates directly adjacent to, and on either side of, a first fuel cell module; a second plurality of mechanical linkages connecting a second pair of compression plates which are directly adjacent to, and on either side of, a second fuel cell module; wherein one compression plate is common to the first and second pairs of compression plates; where a) the first and second fuel cell modules may be maintained under compression, and b) the compression on each fuel cell module may be adjusted essentially independently of the compression on the other.
    • 提供了包括一个或多个燃料电池模块的燃料电池堆,每个燃料电池模块包括至少一个不具有硬停止层的膜电极组件; 两个或多个压板; 以及连接位于至少一个燃料电池模块的任一侧上的一对压缩板的至少多个机械连杆,其可被接合以保持所述一对压缩板之间的预定的间隙距离。 本发明另外提供了一种燃料电池堆,包括:两个或更多个与三个或更多个压缩板交替堆叠的燃料电池模块; 连接第一对压缩板的第一多个机械连接件,其与第一燃料电池模块直接相邻并在其两侧; 连接第二对压缩板的第二多个机械连接件,所述第二对压板直接邻近第二燃料电池模块,并在其两侧; 其中一个压缩板对于第一和第二对压缩板是共同的; 其中a)第一和第二燃料电池模块可以被保持在压缩下,以及b)每个燃料电池模块上的压缩可以基本上独立于压缩而被调节。
