In the current work a mathematical and a simulation study on a three – stage metal hydride hydrogen compressor (MHHC) is presented. Multistage MHHC uses a combination of different materials acting as metal hydrides in order to increase the final compression ratio, while maximizing the absorption capacity of every single stage supply pressure. The performance of a MHHC can be predicted by solving simultaneously the heat, mass and momentum differential equations. The materials used for the current study are LaNi5, MmNi4.6Al0.4 and Ti0.99Zr0.01V0.43Fe0.99Cr0.05Mn1.5. This three – stage compression system yields a pressure ratio of 25:1, for supply conditions 20 °C and 5 bar. The delivery pressure achieved is 115 bar for 100 °C desorption temperature.
