Abstract

Hydrogen storage in two Mg-In-C alloys with different indium concentration cIn was studied in the temperature range from 250 °C to 350 °C after five-years-ageing at room temperature. The both alloys show acceptable cycling stability, however, the storage capacity of the alloys decreased from about 5 wt.% H2 to about 2.5 and 3.1 wt.% H2 by higher cIn and lower cIn concentration, respectively after 5 years. The sorption kinetics degraded much more by high cIn than by lower cIn. PCT isotherms, TPS and DSC patterns were measured for both materials. It was found that the hydrides responsible for hydrogen storage in alloy with higher cIn were slightly more stable.
