Title: Battery cell for a primary battery

A battery cell for a primary battery, particularly a flat cell battery to be activated on being taken into use, e.g., when submerged into water. The battery cell comprises a positive current collector and a negative electrode. A separator layer which, being in contact with the negative electrode, is disposed between said negative electrode and the positive current collector. A depolarizing layer containing a depolarizing agent is disposed between the positive current collector and the separate layer. An intermediate layer of a porous, electrically insulating, and water-absorbing material is disposed next to the positive current collector and arranged in contact with the depolarizing agent.
