A Sodium Borohydride On-board Hydrogen Generator for Powering Fuel Cell and Internal Combustion Engine Vehicles 2001-01-2529

Hydrogen gas, H2, is the environmentally desirable fuel of choice for powering fuel cells and internal combustion engines. However, hydrogen is extremely difficult to store, handle, and transport. One major hurdle to commercializing hydrogen-powered vehicles is providing a way to effectively and safely generate, store, and deliver the large amounts of H2 needed to achieve acceptable vehicle range while minimizing the weight and volume of the storage system. Millennium Cell has developed a novel catalytic process that generates high purity H2 gas from air-stable, non-flammable, hydrogen-rich water-based solutions of sodium borohydride, NaBH4. This on-board system has already been used by Millennium Cell to successfully power a hydrogen powered series-hybrid sport utility vehicle [1], a full size six-passenger sedan with an internal combustion engine running on hydrogen gas, and is currently being installed into a fuel cell vehicle.
