Abstract:
1. A hydrogen generation system comprising: (a) a fuel supply reservoir containing an aqueous solution of at least one metal hydride; (b) a fuel pump configured to withdraw said solution and contact it with a hydrogen generation catalyst thereby generating a fluid product stream comprising hydrogen, water and a salt of said metal; (c) a gas-liquid separator configured to separate said fluid stream into a gaseous product comprising hydrogen and water vapor, and a liquid comprising water and said metal salt; (d) a condenser in fluid flow communication with said gaseous product to condense water therefrom; (e) a condensate recovery zone configured to recover said condensed water; and (f) a mixing zone configured to combine said condensed water with said aqueous solution of metal hydride withdrawn from said reservoir thereby diluting said solution prior to contacting said solution with the hydrogen generation catalyst.
