Intermetallic compounds (IMC), which reversibly absorb hydrogen, are currently the subject of many investigations re their possible use in hydrogen accumulators, thermal machines, thermal pumps and accumulators, sorptional compressors, etc. The dynamics of hydrogen sorption in IMC must be investigated for the analysis and design of such devices. Trends in such studies can be distinguished: the study of the true chemical kinetics of sorption; the investigation of the sorption dynamics in extended IMC layers of dimensions characteristic for practical applications. However, these do not give criteria by which the experimental conditions may be chosen, and often the conditions themselves are not completely described. In connection with this, calculations of the sorption process in which the heat liberation and filtration of hydrogen through the IMC layer are taken into account are of interest both for practical applications and for the elucidation of the conditions in which the process may be regarded as purely kinetic or controlled by the heat and mass transfer in the layer. The authors devote themselves to this aspect in this presentation.
