✦ Synopsis

A novel, simple, convenient, and safe chemical process generates high purity hydrogen gas on demand from stable, aqueous solutions Ž . of sodium borohydride, NaBH , and ruthenium-based Ru , catalyst. When NaBH solution contacts Ru catalyst, it spontaneously 4 4 hydrolyzes to form H gas and sodium borate, a water-soluble, inert salt. When H is no longer required, Ru catalyst is removed from the 2 2 solution and H generation stops. Since this H generator is safer, has quicker response to H demand, and is more efficient than 2 2 2

commonly used H generators, it is ideal for portable applications.
