The article addresses the determination of the physical and material properties of the alloy La₀.₈₅Ce₀.₁₅Ni₅ with a crystalline structure. The properties of the microstructure of the alloy were determined using a scanning electron microscope. The chemical composition was evaluated by energy-dispersive X-ray spectroscopy. An X-ray diffractometer was used to determine the phase composition of the alloy. Next, the alloy sample was subjected to measurements of hardness, thermal conductivity and heat capacity. The storage capacity of hydrogen in the alloy was determined using the pressure concentration isotherms method of measuring. For comparison, the storage capacity was also measured in the amorphous structure of the alloy formed by the melt spinning method.
