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.
