Abstract: Known as one of the most promising
application of metal hydride (MH), the MH compressor can afford
hydrogen with high pressure and high purity. Two AB5 type
multi-component hydrogen storage alloys and vanadium are studied for
the purpose of high pressure compression. A compact compression
system has been built. Each designed small-size reactor contains
seven special stainless-steel pipes. The single stage compressor can
improve the hydrogen pressure from 2 up to 35 MPa with the hydrogen
desorbed per unit mass of 207.8 mL/g. The two-stage compression can
output hydrogen with pressure of 38 MPa steadily in whole 5.7 mol
hydrogen output flow. However, its hydrogen desorbed per unit mass
was only computed to 106.9 mL/g as a result of two reactors used in
the cycle and the output mass of hydrogen increased less.
