TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred System: The hydrogen generation system comprises first compartment comprising the at least one amine borane compound (I), second compartment comprising the at least one ligand-stabilized metal catalyst, where the first or second compartment further comprises an inert solvent and, optionally, a base, and a means for combining the contents of the first compartment with the second compartment so that when the contents are combined, hydrogen is generated; and further comprises at least one flow controller to control a flow rate of the at least one catalyst or the at least one amine borane. The system is fluidly connected to a proton exchange membrane fuel cell (PEMFC). Preferred Components: The base is selected from alkali alkoxide, alkali hydroxide and organic amine.

Preferred Definitions:    R1, R3 and R4=H;    R2=methyl;    n=2-100000.    SPECIFIC COMPOUNDS - 31 Compounds are disclosed as the catalyst (A1), dichloropyridin-2-ylmethanaminebis(triphenylphosphine)ruthenium(II) (I'), chlorohydridobis(2-(diisopropylphosphino)-4-methylphenyl)amidoiridium (III), bis(2-(diisopropylphosphino)ethyl)aminedichlororuthenium(II), dichlorobis(2-(diisopropylphosphino)ethanamine)ruthenium (II), and dichlorothiophen-2-ylmethanaminetriphenylphosphineruthenium(II).    EXAMPLE - Ammonia borane (50.4 mg) and potassium tertiary butoxide (30.7 mg) were added to an L-shaped solid addition tube, which was then connected to a flask (100 ml) which contained chlorohydridobis(2-(diisopropylphosphino)-4-methylphenyl)amidoiridium (III) (9.8 mg). The flask was placed under an argon atmosphere and then dried, degassed tetrahydrofuran (25 ml) was added. The mixture was then placed in a water bath that was heated to 40.7 degrees C and the temperature were allowed to equilibrate for five minutes. The ammonia borane and potassium tertiary butoxide were added by inverting the reaction vessel to allow the solvent to wash the solids into the reaction mixture. The flask was then placed back into the water bath and gas evolution occurred. The result showed that after 30 minutes, 39 ml of the hydrogen was obtained.
