Beschreibung
Zusammenfassung:	An electrochemical cell comprising:- a can (14) defining an interior volume (16), an exterior volume (18), and a orifice (20),- a terminal (22) comprising an external contact (24), a foot (26, and a post (28),- a sealing system (30) for preventing moisture from entering the interior volume, comprising an elastomeric material and having a peripheral part (38) and a central part (40) delimiting an intermediate chamber (42), the peripheral part being compressed between the can and the foot.The sealing system includes a permeation portion (46) comprising a polymer material, and extending through the peripheral part and the central part to allow gas molecules from the interior volume into the intermediate chamber, the central part comprising a tight lip (48) around the post for forming a one-way valve (50) between the intermediate chamber and the exterior volume.
