Abstract: The invention relates to a method for the catalytic hydrogenation of halogenated silanes or halogenated germanes, according to which halogenated monosilanes, oligosilanes or polysilanes, or monogermanes, oligogermanes or polygermanes, are hydrogenated or partially hydrogenated with hydrogenated Lewis acid-base pairs, and the partially halogenated Lewis acid base pairs can be rehydrogenated, especially with further addition of H2 and the heterolysis thereof on the Lewis acid-base pairs, releasing hydrogen halide.

Abstract: The invention relates to a process for preparing hydrogen. According to the invention, monosilane or polysilane is converted to hydrogen at an elevated temperature with steam or oxygen.
Abstract: Process for supplying a fuel cell with hydrogen, which includes the steps:—intermediate storage of (poly)silanes or (poly)silane solutions—transfer of the (poly)silanes to a reaction chamber—reaction or hydrolysis of the silanes or silane solutions in the reaction chamber with an aqueous solution to liberate H2,—removal of the solid and/or liquid reaction products from the reaction chamber,—transfer of the H2 formed to the fuel cell. The invention also relates to a hydrogen generator for fuel cells based on silanes.
