प्रश्न
How do you expect the metallic hydrides to be useful for hydrogen storage?
उत्तर
In metallic hydrides, hydrogen is adsorbed as H-atoms. Due to the adsorption of H atoms, the metal lattice expands and becomes unstable. Thus, when metallic hydride is heated, it decomposes to form hydrogen and finely divided metal. The hydrogen evolved can be used as fuel.
