Abstract
The invention provides an apparatus for maintaining a stack of electrochemical cells in an electrochemical generator in a state of compression. The apparatus includes a spring plate and a pressure plate, the spring plate being characterized by a series of resilient lateral extensions acting as springs. The pressure plate is operative to cooperate with the spring plate for applying pressure to the stack of electrochemical cells. Also provided is an electrochemical generator comprising a stack of electrochemical cells positioned within an enclosure and an apparatus positioned within the enclosure for maintaining the stack of electrochemical cells in a state of compression.
