- Аннотация: Recently most of the research activities in the field of metal hydride technologies are aimed to the improvement of hydrogen storage material characteristics (capacity, operation temperature, pressure, etc.). Much less attention is paid to the problems appearing during design of metal hydride energy systems. Most of common investigation techniques of hydrogen storage materials properties involve the testing of small-scale samples (less than 10 g) whereas pilot devices for hydrogen energy system must contain kilograms of storage material. Change of the alloy cell volume during hydrogen absorption or desorption leads to stresses of the alloy/hydride lattice. In the large-scale systems inside the bulk fill the reciprocal influence of particles inhibits the lattice relaxation. This process affects the thermodynamic characteristics of hydrogen absorption and desorption. The experimental data of present work allows to suppose that properties of LaNi5-based storage materials depend on their scale and geometry.
