Abstract

Dihydrogen generator ( 5 ) comprising a chamber ( 10 ) and a catalytic system ( 15 ), the catalytic system being rigidly fastened to the chamber in a removable manner and comprising a catalysis housing ( 25 ) containing a catalyst ( 205 ) for the reaction for generating dihydrogen from a reagent ( 405 ) chosen from a hydride, a liquid organic hydrogen carrier and mixtures thereof, the chamber defining a chamber internal space ( 45 ), the catalysis housing being positioned at least partly in the chamber internal space.

First claim

The invention claimed is:

1 . A dihydrogen generator comprising:
an enclosure; and a catalytic system, the catalytic system being secured rigidly and removably to the enclosure and comprising a catalysis housing containing a catalyst for a reaction of generating the dihydrogen from a reagent chosen from a hydride, a liquid organic hydrogen carrier and mixtures thereof, the enclosure defining an enclosure interior space, the catalysis housing being placed at least in part in the enclosure interior space, and the generator comprising a reservoir for containing a liquid, the reservoir comprising a reservoir wall that is fluidtight with respect to liquid and permeable to dihydrogen, the catalytic system being placed at least in part in the reservoir.

2 . The generator as claimed in claim 1 , the catalytic system being secured to the enclosure using one of magnets, screw-fastening and snap-fastening.

3 . The generator as claimed in claim 1 , the enclosure comprising an opening providing access to the enclosure interior space, and the catalytic system being configured to be introduced into and extracted from the enclosure interior space via the opening providing access to the enclosure interior space when the catalytic system is being fitted to and removed from the enclosure, respectively.

4 . The generator as claimed in claim 3 , the catalytic system comprising a plug mounted removably on the enclosure.

5 . The generator as claimed in claim 4 , the plug plugging the opening providing access to the enclosure interior space.

6 . The generator as claimed in claim 4 , the enclosure defining another opening providing access to the enclosure interior space, the plug plugging the other opening providing access to the enclosure interior space.

7 . The generator as claimed in claim 4 , the catalysis housing being positioned at a distance from the plug.

8 . The generator as claimed in claim 1 , the catalysis housing comprising first and second components which together define a catalysis chamber, the catalyst being housed in the catalysis chamber, the first and second components being configured to move relative to each other between a closed position in which the catalysis chamber is isolated from the enclosure interior space and an open position in which the catalysis chamber is in fluidic communication with the enclosure interior space.

9 . The generator as claimed in claim 1 , the catalytic system comprising an information module configured to acquire and store information relating to a state of the catalytic system.

10 . The generator as claimed in claim 1 , the catalyst being at least one metal selected from cobalt, nickel, platinum, ruthenium and alloys thereof.

11 . The generator as claimed in claim 1 , the enclosure comprising a vessel and a lid configured to be fixed rigidly and removably to the vessel and plugging the vessel.

12 . The generator as claimed in claim 11 , the lid being one of screw-fastened and snap-fastened onto the vessel.

13 . The generator as claimed in claim 12 , the lid comprising a receptacle and a covering membrane hermetically plugging the receptacle, the receptacle being configured to contain a reagent.

14 . The generator as claimed in claim 13 , comprising a piercing member configured to pierce the covering membrane.

15 . The generator as claimed in claim 14 , comprising a piercing actuator configured to move the piercing member to pierce the covering membrane.

16 . The generator as claimed in claim 14 , the lid comprising the piercing member.

17 . The generator as claimed in claim 1 , the catalytic system being secured to the enclosure using a bayonet locking type device.

18 . The generator as claimed in claim 11 , the lid being secured to the vessel using one of magnets and a bayonet locking system.
