Abstract

The metal hydride electrodes are of a particular interest due to their potential and practical application in batteries. A large number of the hydrogen storage materials have been characterized so far. Nevertheless only selected composite structures were synthesized. This paper deals with the effect of the hydrogen sorption capability and electrochemical characterisation of specific AB5 alloy composites - AB5 with SiO2, B2O3, WO3 and C. The hydrogen storage capacity and kinetics of hydrogen sorption-desorption in the solid phase/gas and solid phase/electrolyte solution systems are presented.
