Abstract
The hydrogen-storage system Mg2Ni0.75Fe0.25-Mg (molar ratio is 2:1) ha s been successfully synthesized by the replacement-diffusion method (R DM). A study of the hydrogen desorption process was carried out. The r esults indicated that the pressure-composition isotherm (P-C-T) charac teristics, plateau pressure and storage capacity change with temperatu re. The present system corresponds to a new hydrogen storage material with an optimum storage-capacity (3.3 wt.%). (C) 1997 Elsevier Science S.A.
