Hydrogen storage in a metal hydride bed, uses an intermetallic alloy that can absorb efficiently high amounts of hydrogen by chemical bonding resulting to metal hydrides. This alloy is capable of absorbing and desorbing hydrogen while maintaining its own structure. The heat, mass and momentum transfer in a metal-hydride reactor is mathematically described by energy, mass and momentum balance equations. These equations are solved to simulate the performance of the metal hydride reactor, which is very important for the proper design and operation of the unit. The solution of these differential equations was performed using the COMSOL multiphysics software.
