## Abstract

It is described a device for the production of hydrogen gas by a reactor where aqueous solutions of metal borohydrides are hydrolyzed on catalysts based on ferromagnetic metals. Apparatuses containing said device are also described.

## Claims

### Claim at position 1

-9. (canceled)

### Claim 10

Device comprising: a gastight tank (13), a pump (11), a heat-exchanger (18-21) and a reactor (10) for the production of hydrogen gas by catalyzed hydrolysis of aqueous alkaline solutions of alkaline metal or alkaline-earth metal borohydrides wherein said reactor (10) is constituted by a hollow body, essentially cylindrical in shape, (1) sealed at an end while the opposite end is open and equipped with a cap (2) where said cylinder contains holes (5) for the discharge of the exhausted solution and contains one or more permanent magnets (4) coated by ferromagnetic catalysts directly anchored to said permanent magnets held by an extractable guide (8) which allows their easy extraction and insertion into the cylinder characterized in that it comprises a temperature sensor and in that said reactor (10), pump (11) and temperature sensor are inserted into the tank (13).

### Claim 11 (depends on 10)

Device according to claim 10 where said ferromagnetic catalysts are selected from the group consisting of cobalt or nickel powders, cobalt- or nickel Raney, alloyed Co—Ni Raney, cobalt or nickel nanoclusters, cobalt or nickel wires, nano- or micro-structured aggregates of nickel with nickel borides, nano- or micro-structured aggregates of cobalt with cobalt borides, and mixed aggregates of cobalt and nickel with cobalt borides.

### Claim 12 (depends on 10)

Device according to claim 10 wherein the hydrogen produced by catalyzed hydrolysis of aqueous alkaline solutions of alkaline metal or alkaline earth-metal borohydrides leaks from the reactor through holes (6) and meets an aerosol abatement system (7) for a first separation of the gas from the solution and the recovery of the latter.
