Surface properties of V 40(TiCr) 51Fe 8Mn alloy during hydrogenation/dehydrogenation cycles

Andreas Züttel

The bcc alloy V40(TiCr)51Fe8Mn shows a high reversible hydrogen capacity of 2.22 mass% at room temperature and is therefore expected to be applied as a hydrogen storage material. During the first 10 hydrogenation/dehydrogenation cycles, the capacity decrea ...
