Abstract: One of these devices comprises: a reaction chamber with cold plasma (10b), for producing the reforming of a primary mixture consisting of fuel gas (hydrocarbon or alcohol), as well as oxygen and/or water vapour, thus producing a secondary mixture containing in particular hydrogen, carbon dioxide and carbon monoxide; an intake piece (18) for mixing these constituents, co-operating with a burner (42) and an associated combustion chamber (40) to bring the resulting primary mixture to a high temperature, before it is introduced into the reaction chamber (10a); a ring-shaped chimney (48) enclosing this chamber for maintaining it at a relatively high temperature; a high frequency alternating high voltage source (58), modulated by brief periodical low frequency pulses and electrodes (62-66) for generating silent discharges, in the reaction chamber (10b) thus generating a cold plasma producing a high chemical reactivity to the gas mixture present; a membrane (12) with high selective permeability for extracting the nascent hydrogen, arranged between the chamber (10b) and a chamber for collecting the hydrogen (14); a thermal insulating sheath (50) enclosing the whole set. The invention is applicable to PEM type fuel cells, fitted on electric vehicles or on portable generator set.
