Hydrogen is one of the most promising energy carriers, which is considered for various applications, e.g. in power electric vehicles or hybrid electric vehicles. The main advantage of hydrogen is no direct emission of CO2 and NOx during its using as a fuel. The main problems that limit wide application of hydrogen are its transport and storage. H2 gas is highly inflammable and therefore is dangerous in confined spaces. One of the promising method of safe hydrogen storage is its chemical or physically combined storage in other materials e.g. metal hydrides. The metal hydride can hold between 1% and 7% of hydrogen by weight, depending on the alloy composition. As a hydrogen storage material, the metal hydride is very efficient and delivers much better volumetric efficiency than hydrogen stored in a liquid state. The performance of the metal hydride electrode depends on the composition and the microstructure of the active material. In consequence, the majority of the studies on improving the MH electrode performance are focused on these aspects. In our Laboratory we investigate new useful materials for hydrogen electrochemical storage. Our works are divided into two fields: modification of electrode materials for nickel-
