About Millennium Cell: Founded in 1998, Millennium Cell is based in Eatontown, NJ, and has developed a multi-faceted patent portfolio, which the company is pursuing in the United States and internationally surrounding a proprietary process called Hydrogen on Demand(. The Hydrogen on Demand( system safely generates pure hydrogen from environmentally friendly raw materials. In the process, the energy potential of hydrogen is carried in the chemical bonds of sodium borohydride, which in the presence of a catalyst releases hydrogen. The primary input components of the reaction are water and sodium borohydride, a derivative of borax. Borax is found in substantial natural reserves globally. Hydrogen from this system can be used to power fuel cells or fed directly to internal combustion engines. Millennium Cell also has a patented design for boron-based longer-life batteries.
