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 controlling an
electrical or light energy source which supplies an ignition control
signal causing energy to be applied to the input of a series of
connecting means, respectively associated with each of the pyrotechnic
elements. A single pyrotechnic element is connected to the energy source
at any one time, the elements preceding it having already been used. The
connecting means can be sensitive to temperature or to pressure.
