In this paper, the electrochemical hydrogen storage in nanocomposite materials was studied. Multi-Walled Carbon Nanotubes (MWCNTs) electrode was prepared by mixing with special composite. The optimum ratio of MWCNTs was estimated 30-70% (w/w) in the composite material. MWCNTs were synthesized by Chemical vapor deposition (CVD). The nanocomposite was homogenized by microwave. Cyclic voltammetry (CV) was applied to study the behavior of electrode. Ni nanoparticles were electrodeposited on working electrodes via dual-pulse method. Voltammograms indicated that, Ni nanoparticles have electrocatalytic effect on hydrogen storage capacity.
