Abstract

A safe, simple, compact process generates high-purity hydrogen gas on demand from base-stabilized, aqueous solutions of sodium borohydride, NaBH₄, by using a ruthenium, Ru, catalyst. These NaBH₄-based solutions can store up to 7% hydrogen by weight. NaBH₄ solutions do not generate significant amounts of H₂ gas under ambient conditions. However, when in contact with Ru catalyst, NaBH₄ solutions spontaneously hydrolyze to form H₂ gas and sodium borate, a water-soluble, inert salt. When Ru catalyst is separated from the NaBH₄ solution, H₂ generation stops. This H₂ generator promises to be safer, have quicker response to H₂ demand, have a greater H₂ storage efficiency, and be more easily controlled than commonly used H₂ storage devices or generators. Nonflammable NaBH₄ solutions can be easily coupled to provide H₂ to internal combustion engines or fuel cell power systems.
