We report on a Sievert-type experimental apparatus for the study of hydrogen storage in metals forming the hydride phase. The apparatus is realized by only using commercial components and allows the study of the hydrogen absorption and desorption kinetics as well as the determination of the pressure–composition ( P–C ) diagram of the material–hydrogen system. The apparatus can operate over a wide range of temperature, 300–700 K, and H 2 pressures, 1–80 bar. The H 2 storage efficiency can be measured with a good accuracy ~3%. The experimental errors in the hydrogen absorption and desorption kinetics are ~1% and 6%, respectively.
