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.
