Tóm tắt

 The conclusions of this presentation are: (1) Amine boranes potentially can be used as a vehicular hydrogen storage material. (2) Purity of the hydrogen stream is critical for use with a fuel cell. Pure H{sub 2} can be provided by carefully conditioning the fuel (encapsulation, drying, heating rate, impurities). (3) Thermodynamics and kinetics can be controlled by conditioning as well. (4) Regeneration of the spent amine borane fuel is still the greatest challenge to its potential use. (5) Addition of hydrocarbon-substituted amine boranes alter the chemistry dramatically. (6) Decomposition of the substituted amine borane mixed system favors reaction products that are more potentially easier to regenerate the hydrogenated fuel. (7) t-butylamine borane is not the best substituted amine borane to use since it releases isobutane
  however, formation of CNBH{sub x} products does occur.
