Hydrogen storage in thin film metal hydrides

摘要: Sandwich films were prepared by vapour deposition on quartz crystals or polycrystalline aluminium foil, e.g. quartz/V(1 μm)/Pd(100 nm) and Al(20 /V(10 nm). The vanadium can be hydrided almost reversibly from the gas phase within seconds to VH0.5 at 300 K a hydrogen pressure of 1 bar min VH1.8 30 bar. known diagrams V-H2 system reproduced. Al/Pd/V/Pd used in prototype storage containers: 2% mass fraction was stored, similar TiFe hydride storage, but much higher heat exchange rate attained.
