The main subject of the present invention are solid compounds capable of generating hydrogen by a self-sustaining combustion reaction. Their composition comprises borazane and/or polyaminoborane and at least one inorganic oxidant, advantageously chosen from ammonium nitrate, alkali metal nitrates, alkaline-earth metal nitrates, metal nitrates, metal oxides, oxidants of the family of dinitramines and mixtures thereof. It also relates to the generation of hydrogen by self-sustaining combustion of at least one such compound.
