Abstract
Efficient hydrogen generation system was suggested based on Ammonia-Borane (NH3BH3) with 19.5wt% hydrogen in its molecule. From the understanding of intermolecular hydrogen generation during thermolysis, improved hydrogen generation at lower temperature by increasing packing density was confirmed by mass spectroscopy connected to thermolysis system. More efficient hydrogen generating system utilizing exothermic reaction was investigated by applying local heating method. Exothermic reaction heat from decomposition and packing density for the heat propagation in the specimen were the parameters to enhance hydrogen generation capacity and efficiency of the system in the system-wise approach for hydrogen storage. 13.8 wt% of hydrogen (material-based) was generated with local heating supplied 50 V for 1 min.
