Abstract
The module is designed for supplying hydrogen to a fuel mini-cell, wherein hydrogen is gradually released by combustion of elements made of pyrotechnic material, after ignition. A device for sequential control of ignition of the pyrotechnic elements comprises a circuit (13) controlling an electrical or light energy source (11) which supplies an ignition control signal causing energy to be applied to the input of a series of connecting means (12), respectively associated with each of the pyrotechnic elements (Ei). A single pyrotechnic element (E2) is connected to the energy source at any one time, the elements (E1) preceding it having already been used. The connecting means (12) can be sensitive to temperature or to pressure.
Claims19
A module for supplying hydrogen characterized in that it comprises means for triggering and controlling gradual release of hydrogen in a fuel mini-cell, the hydrogen being supplied, after ignition of the latter, by combustion of a plurality of pyrotechnic elements (Ei) integrated in the module, said means comprising an energy source (11) and a device for sequential control of ignition of the pyrotechnic elements comprising means for selectively connecting the energy source to an ignition element of each of the pyrotechnic elements, the connecting means comprising means (12, 18, 33) for connecting a single ignition element associated with a predetermined pyrotechnic element to the energy source during a preset ignition time (t0-t1), and for automatically preparing connection of another pyrotechnic element to the energy source after the ignition time.
