Ball-milling of hydrogen storage alloy to obtain nanoparticle is already known to improve the hydrogenation behaviour of AB5-type and other metal hydrides [4, 5, 6, 7].
In this work, the effects of adding buffer agents into aqueous electrolytes on the hydrogen adsorption/desorption behaviour at/within activated carbon are systematically investigated for the negative electrode of asymmetric supercapacitors.
The hydrogen sorption behaviours and stability of the TiO2NT/Pd nanocomposites were investigated and compared with nanoporous Pd networks that were deposited on a bulk titanium substrate (Ti/Pd) using cyclic voltammetry (CV) and chronoamperometry (CA).
The combination of thermokinetic simulations with hydrogen trapping behaviours is the first of its kind and presents a means to incorporate the effects of various microstructural features, with respect to hydrogen migration and trapping, in the design of hydrogen embrittlement resistant steels.

In the current study, a CFD based approach is proposed to evaluate the dispersion behaviour of hydrogen gas after a release from a hydrogen fuel cell car in an enclosed area.
It is expected that this work could provide important fundamentals in understanding mechanical behaviour of hydrogen stored SWNCTs subjected to compression that could assist in the development of effective on-board hydrogen storage systems for fuel cells.
A particular cathodic charging technique was used to evaluate the behaviour of hydrogen on Fe25.66Ni0.31C alloy.
