“…Since then many research groups have been engaged in the area of hydride hydrogen compression. Silvaa [5] reported an industrial prototype of a hydrogen compressor based on FeTi metallic hydride technology, which desorbs the pressurized hydrogen of 10 MPa at 250 • C. The pilot sample of metal hydride hydrogen compressor was reported by Shmal'ko et al [6]. The compressor consists of two two-stage compressing modules, in which LaNi 4.5 Mn 0.5 and LaNi 5 are used as 'low temperature' and 'high temperature' hydride-forming intermetallides, respectively, and the pressure of output hydrogen reached 15 MPa.…”
