<p>An apparatus for maintaining a stack of electrochemical cells of an electrochemical generator in a state of compression. The apparatus comprises a pair of holding members, each one of the holding members being positioned at a respective extremity of the stack of electrochemical cells. The apparatus also comprises anchoring devices for maintaining the holding members at a predetermined distance from one another to thereby maintain the stack of electrochemical cells in a state of compression. Also provided is an electrochemical generator comprising an enclosure, a stack of electrochemical cells positioned in the enclosure, and an apparatus as defined above for maintaining the stack of electrochemical cells in a state of compression.</p>
