The cell (1) for storing at least one set (2) of products (20), particularly a set of products arranged on at least one storage support (3), said cell comprising ventilation means (4) for creating a rear-to-front air flow (A) circulating in the housing (14) from the rear to the front of the housing or for creating a front-to-rear air flow (B) circulating in the housing (14) from the front to the rear of the housing, and at least one first sealing device (5 or 6) comprising a first flexible sealing element (50 or 60) that can inflate in relation to one of the walls (10, 11, 12) of the cell and towards the inside of the housing (14) under the effect of an air pressure which is generated in the housing (14) by said air flow (A or B). The first sealing device (5 or 6) comprises at least one second sealing element (52 or 62) that can be switched between an inactive configuration and an active configuration in which it exerts a mechanical pressure on part of the first flexible sealing element (50 or 60), said mechanical pressure being oriented towards the inside of the housing (14) and allowing said first flexible sealing element (50 or 60) to be distanced from said wall (10, 11, 12) of the cell in relation to which said first flexible sealing element (50 or 60) can inflate. The cell comprises actuating means that allow the second sealing element (52 or 62) to be switched into its active configuration.
