The present invention relates to solid compounds which generate hydrogen by combustion, and to a method for generating hydrogen based on the combustion of said compounds. Said compounds have a composition which includes at least one inorganic borohydride, selected from alkali borohydrides, alkaline-earth borohydrides and mixtures thereof, and at least one inorganic oxidant. Characteristically, said composition comprises sulfur. Said method is advantageously implemented for supplying hydrogen to a fuel cell.

Solid hydrogen source compounds and method for generating hydrogen

The invention relates to a solid composition which can decompose with the generation of hydrogen according to a self-sustaining combustion reaction after initiation of this reaction by an appropriate heat source, this composition being characterized in that it comprises an alkali metal borohydride or alkaline earth metal borohydride and a perchlorate-based oxidizing salt corresponding to the general formula SClOin which X represents the NHgroup, an alkali metal or an alkaline earth metal.

Solid composition, hydrogen generating method, and proton exchange membrane fuel cell

The technical field of the invention is that of microactuators designed for mechanical, chemical, electrical or thermal functions in microsystems, for microelectronic applications such as chips, or biomedical applications such as cards incorporating microfluidics. The invention concerns a microactuator comprising a chamber machined in a solid support and containing a pyrotechnic charge. Said microactuator is essentially characterised in that the chamber is partly delimited by a deformable membrane, such that the gases emitted by combustion of the pyrotechnic charge enable to increase the volume of said chamber by deforming said membrane while maintaining intact the solid walls of the chamber.
