Solid Borazane Hydrogen Storage and Generation System

Lynntech proposes a hydrogen generator, coupled with Lynntech's previously developed alkaline fuel cell systems for portable applications, that offers advantages over battery power in size, operational time between refueling, and operations in military environments. With 19.6 wt% hydrogen, borazane (NH3BH3), a water soluble, non-cryogenic solid, is one of the most hydrogen rich solids available, and a promising means to deliver hydrogen for use in fuel cells. Lynntech offers a unique solid borazane based hydrogen generator capable of scalable rates of hydrogen production, real time control, including rapid start/stop operation, eliminating the need for heavy high pressure hydrogen storage vessels. For small fuel cell applications, the solid borazane based hydrogen generator is ideally suited for alkaline fuel cell systems, which are not affected by trace amounts of ammonia produced, but can also be used with PEM systems after the removal of the trace ammonium by a passive chemical filter, a simple process compared to hydrocarbon reformate purification. In Phase I, a first generation prototype hydrogen generator based on solid borazane will be built and tested in a variety of military environments, with parallel studies focusing its integration with Lynntech's scalable alkaline fuel cell system for portable applications.
