Abstract
The present invention discloses new methods for synthesizing ammonia borane (NHBH, or AB). Ammonium borohydride (NHBH) is formed from the reaction of borohydride salts and ammonium salts in liquid ammonia. Ammonium borohydride is decomposed in an ether-based solvent that yields AB at a near quantitative yield. The AB product shows promise as a chemical hydrogen storage material for fuel cell powered applications.
