Abstract

An electrochemical cell (10) comprising:- a can (12),- an electrical terminal (18) defining an axis (X) and forming a housing (20,- a plunger (24),- an upper O-ring (26) and a lower O-ring (28) located on an upper extremity (30) of the plunger along the axis and on a lower extremity (32), and surrounding the axis, the terminal, the plunger, the upper O-ring and the lower O-ring delimiting an intermediate chamber (60).The lower O-ring forms a lower sealing valve between an interior volume (14) and the chamber. The upper O-ring forms an upper sealing valve between the chamber and an exterior volume (16). The plunger is movable axially with respect to the terminal between an equilibrium position and two working positions in order to let excess gas moving from the interior volume to the exterior volume via the chamber while preventing moisture from doing the opposite.
