Abstract (en)
[origin: WO2014091127A1] The subject matter of the present invention is a pyrotechnic process for providing very highly pure hydrogen (G) and also a device (100) suitable for implementing said process. Said process comprises: the combustion of at least one solid pyrotechnic charge which generates hydrogen-containing gas (4a, 4b, 4c, 4d) for the production of a hot hydrogen-containing gas (G1) under pressure, containing at least 70% by volume of hydrogen; and the purification of at least one part of said hydrogen-containing gas (G1) under pressure, by passage through a metallic membrane for separating the hydrogen (9) maintained at a temperature above 250°C, advantageously between 300 and 600°C, so as to obtain, at the outlet of said membrane (9), a hydrogen-containing gas (G) containing at least 99.99% by volume of hydrogen.
