Structural and methodical features of the installation for the investigations of hydrogen-sorption characteristics of carbon nanomaterials and their composites

Abstract

The laboratory setup for investigations of hydrogen capacity of materials has been created at the Institute for Problems of Materials Science of NAS of Ukraine. It completely meets the modern requirements for the experimental equipment of this class. The setup design makes it possible to investigate hydrogen-sorption characteristics of different materials with low specific density, including nanocarbon structures and composites on their basis, by the volumetric method in the pressure range between 0.01 and 16 MPa H2 and at temperatures from 77 K to 1273 K. The setup provides a sufficient degree of accuracy. It is equipped with a metal-hydride unit for hydrogen storage/compression. The design and service conditions of this device are discussed. © 2007 Springer.
