ABSORPTION OF HYDROGEN BY MMNI(5) ALLOYS

In recent years much attention has been paid to the development of hyd rogen absorbing alloys in which the pure rare-earth metals are substit uted by a more accessible raw material-mischmetal, but the composition of mischmetal can vary widely. The properties of MmNi(5)H(x) (hydroge n capacity, hydrogen desorption equilibrium pressure at given temperat ure) depend on the composition of mischmetal and the mode of preparati on of the alloys. In this work the results of the investigation of the interaction of four alloys of MmNi(5+/-delta) are presented. Copyrigh t (C) 1996 International Association for Hydrogen Energy
