- a compaction step and a compression step are distinguished in that a compaction step has the effect of modifying the density of the compacted material, and in that a compression step does not substantially modify the density of the compacted material. material.
- the compression step is intended to apply the intermediate elements on each other, so that these intermediate elements are found in close contact without play between them.
- the method according to this first embodiment comprises only one compaction step, so that it makes it easy to control the density of the material.
- This axial compression of the intermediate elements has the effect of extending radially these intermediate elements, so that the contact between these intermediate elements and the inner wall of the shell is provided.
- it ensures optimal contact between the stacked intermediate elements, and between the intermediate elements and the inner wall of the shell.
- This optimal contact ensures a good diffusion of heat in the cartridge.

- the method then comprises a step 1 10 for producing an intermediate element, during which the material obtained at the end of step 100 of supply is covered by at least one thermally conductive sheet, so as to form the element intermediate.
- This covering step is described with reference to FIGS. 2 to 4.
- This step 1 10 is performed using a first press 12 having a fixed portion 12A and a movable portion 12B.
- the first press 12 comprises a mold 14, having a lower portion 14A, carried by the fixed portion 12A of the first press
- the mold 14 has a general shape of revolution about an axis.
- the lower portion 14A has a substantially frustoconical male zone 15A
- the upper portion 14B has a female zone 15B complementary to the male zone 15A.
- the first press 12 notably makes it possible to form thermally conductive sheets, preferably made of aluminum, by providing a flat sheet which is pressed into the mold 14.
- This lower sheet 16A also defines a circular side face 22A.
- the lower face could have a relief different from that previously described.
- the mold 14 is then filled with the material 23.
- This material 23 is then compacted at a first pressure, for example between 1 and 2 tl cm 2 , as shown in FIG. 4, to a density of between 1.25 and 1.4 Kg / decimetres 3 .
- the height of the material 23 passes for example from 65 mm to 20 mm.
- Step 1 10 terminates advantageously by the addition of an upper sheet 16B, defining an upper face 18B substantially parallel to the lower face 18A.
- the upper face 18B comprises a substantially frustoconical male portion 20B of complementary shape of the frustoconical female portion 20A.
- the intermediate element 24 may not have a top sheet
- FIG. 5 shows an intermediate element 24 thus obtained at the end of this step 1 10.
- each intermediate element 24 could, as a variant, comprise a central axial orifice, allowing the passage of a heating resistor within the cartridge 10 during its use.
- FIG. 8 shows a press
- This press 12 is similar to that described above, but also comprises a central rod 25 extending longitudinally in the mold 14.
- the first 14A and second 14B mold parts have longitudinal orifices for passage of the central rod 25.
- the intermediate element 24 obtained is then extracted from the first press 12 to be stacked in a second press 26 with other intermediate elements 24, during a step 120 of stacking these intermediate elements 24.
- an extraction device 27 comprising an arm 27A movable between the first 12 and second 26 presses, the arm 27A being provided with means 27B for gripping the intermediate element 24.
- the arm 27A deposits the intermediate elements 24 in a shell 28 of cartridge, so as to make a stack of these intermediate elements 24 in the shell 28.
- the shell 28 has a generally cylindrical inner diameter greater than the diameter of the intermediate elements 24.
- the second press 26 comprises a support rod 30, intended to receive the stack of intermediate elements 24.
- the support rod 30 comprises a head 32 of complementary shape to that of the lower face 18A of each intermediate element 24, so that the stack is stably maintained on this head 32.
- the stacked intermediate elements are subjected to the application of a second pressure, in the shell 28 by the second press 26.
- the second pressure is lower than the first pressure.
- this step 130 of applying a pressure is a compression step, not substantially modifying the density of the material.
- the second pressure is preferably less than one-tenth of the first pressure.
- the pressure applying step 130 is a second compaction step, changing the density of the compacted material.
- these intermediate elements 24 extend radially during their compression, until they come into contact with the inner wall of the shell 28. This compression does not significantly change the density of the intermediate elements 24.
- the shell 28 has an inside diameter of 102 mm, and each intermediate element has a diameter of 101.5 mm before compression.
- the intermediate elements 24 are stacked without clearance between them, and without play with the inner wall of the shell 28.
- the stacking and compression can be performed in one go or in several successive operations.
- the intermediate elements 24 deform little during compression, so that the risk of loss of material 23 during compression are limited.
- the intermediate elements 24 are reversibly connected with the shell 28.
- the ammonia has been extracted from the intermediate elements 24, it is possible to extract the intermediate elements 24 from the shell 28 to replace them, and thus reuse the shell 28 for the production of a new cartridge 10.
- the method comprises a step 140 of closing the shell by upper and lower lids 34.
- the upper cover 34 has a shape complementary to that of the upper face 18B of the intermediate end member 24 with which it is in contact.
- the lower cover 36 may also have a shape complementary to the shape of the lower face 18A of the intermediate end member 24 with which it is in contact, or, as shown in Figure 7, a planar shape.
- the cartridge 10 comprises a connector 38, intended to be connected with a pipe (not shown) for collecting the NH 3 gas extracted from the material during the use of the cartridge.
- this connector 38 also forms a spacer between the lower cover 36 and the lower face 18A of the intermediate end element 24.
- the closing step is performed by crimping, or by stapling the covers 34 and 36 at each end of the shell 28.
- crimping step or stapling unlike a welding step generally used in the state of the art, does not produce heat, and therefore does not cause the desorption of ammonia stored.
- a seal is provided between the shell 28 and each of the covers 34, 36.
- the compression step 130 could alternatively be carried out by restricting the shell 28, that is to say by radial compression, so as to reduce its diameter until the intermediate elements 24 are compressed radially.
- intermediate elements 24 could have another shape, for example polygonal cross section.
- each intermediate element 24 is shaped so that its concave portion 20A has substantially a shape of sphere portion.
- Such a shape makes it possible to optimize the filling volume of the cartridge 10, and to better distribute the compacting pressure on the lower surfaces 18A and 18B of each intermediate element 24.
