The weight efficient hydrogen storage devices will be developed by using the selected and performance-optimised materials. The final milestone of the project was focused on the development and optimization of the operation conditions for NaBH4 hydrolysis. Kinetics of hydrogen evolution from sodium borohydride solution with different catalytic additives was studied. It was found that nano-Pt possessed the highest activity among the investigated catalysts. At the same time we demonstrated that the use of Co nanoparticles on a zeolite substrate can be promising catalyst, taking into account lower cost and almost linear dependence of the hydrogen evolution rate on the concentration. The prototype of the portable power source that uses PEM fuel cell operating on hydrogen obtained by NaBH4 solution hydrolysis was developed. Product Description popup.authors Berezovets Vasyl V.
