  "textContent": "The pressure compensating device has a gas passage opening (130) and a membrane element (116) with a gas permeable membrane through which the gas passage opening is locked. The gas permeable membrane is deformable depending on a change in the internal pressure. An emergency degassing unit is provided, which is so formed and arranged that it damages the membrane by reaching a critical deformation of the membrane. The membrane partially releases the gas passage opening for emergency degassing of the housing. An independent claim is included for an electrochemical device with multiple electrochemical cells.",
