Abstract
The invention relates to solid compositions that can decompose generating hydrogen in a self-sustaining combustion reaction after this reaction has been initiated by an appropriate heat source. These compositions comprise an alkali metal borohydride and an oxidizing mineral ammonium salt of formula NH.sub.4Y, in which Y represents a group consisting only of nitrogen and oxygen. The ratio of the weight content of alkali metal borohydride to the weight content of the salt of general formula NH.sub.4Y is between 1 and 4. Thus, high hydrogen mass yields are obtained, of around 8 to 14%, thereby making it possible to reduce the size and the weight of the hydrogen generators used in certain systems, especially in proton exchange membrane fuel cells.
