Abstract
Hydrogen production through hydrolysis shows a promise as a green and sustainable energy source that can be used for urgent need of energy on-board. This study presents a novel approach to boost the speed of hydrolysis reactions by utilizing Mg2NiH4 powder. The approach involves ball milling with NaCl and fused silica additives, that open additional active areas and accelerate the hydrolysis process. A comprehensive analysis encompasses morphology, elemental mapping, chemical bonding, structural changes, and surface area determination of the prepared powders. The hydrolysis reactions is performed using acetic acid solutions with different molarities (0.25 M, 0.12 M, and 0.06 M), as well as tap water. The impact on kinetics is profound, with reaction rates varying between 600 and 3000 ml/min during the initial seconds for different powders. Moreover, the study examines the application of such hydrolysis system for electricity generation through a proton-exchange membrane fuel cell.
