CARTRIDGE FOR PYROTECHNICAL GENERATION OF HYDROGEN AND METHOD FOR CONTROLLING THE CHARGE OF AN ACCUMULATOR IN A PORTABLE DEVICE

摘要

The invention relates to a cartridge (1) for pyrotechnical generation of hydrogen, for supplying a fuel cell in a portable electronic device, comprising solid hydrogen storage bodies, formed by long cords (4), made from a pyrotechnical material which releases gaseous hydrogen on combustion. The cords are integrated in a support (5) of inert material. Ignition means (3) are arranged close to the cord (4) such that a combustion front, corresponding to a section of the cord, runs along the cord. The support (5) can comprise channels in which the cords (4) are arranged.
