Ammonia-Borane and Related N-B-H Compounds and Materials: Safety Aspects, Properties and Applications

摘要

Amine-borane complexes have great potential for use as a key component in hydrogen storage fuels due to their stability and the high gravimetric content of hydrogen in these compounds. For example, the simplest complex, ammonia-borane (H(3)NBH(3)), contains 19.5 wt% H, which is higher than the wt% H in LiBH(4). The 2015 DOE goal is to develop and achieve an on-board hydrogen storage system with at least 9 wt% H. Thus, it appears that an amine-borane-based system has reasonable potential to meet this goal. However, many issues need to be addressed. Technical and economic issues related to the possible use of ammonia-borane (AB) for the generation of hydrogen for fuel cell applications were evaluated in prior DOE funded reports.
