Hydrogen generation system

Abstract

Hydrogen generation system. A source of sodium borohydride is carried on a flexible substrate that moves from a feed roll to a takeup roll. A reaction among sodium borohydride, a catalyst and water evolves hydrogen and forms a by-product that is removed from the reaction area.

What is claimed is:  
     
         1 - 14  (Canceled)  
     
     
         15 . Fuel cell system comprising: 
 a fuel cell; and    a hydrogen generator connected to deliver hydrogen to the fuel cell, the hydrogen generator comprising:    means for contracting sodium borohydride, water, and catalyst; and    means for moving reactants away from a reaction zone.    
     
     
         16 . Electronic devices system comprising; 
 a hydrogen generator for generating hydrogen;    a fuel cell for receiving the hydrogen to generate electricity; and    an electronic device connected to receive electrical energy from the fuel cell, the hydrogen generator comprising;    means for contracting sodium borohydride, water, and catalyst to release hydrogen;    and means for moving reactants away from a reaction zone.    
     
     
         17 . Fuel cartridge comprising; 
 replaceable structure including sodium borohydride, water, and a catalyst; and    means for contracting the sodium borohydride, water, and catalyst to release hydrogen and further including means for moving reactants into and away from a reaction zone.
