Abstract
Entrained metal hydride particle are removed from a flow of hydrogen from a Mg-based hydride storage unit using not only a particle filter but improvements for reducing or eliminating drastic changes in flow. In addition to or alternative to removal of entrained metal hydride particles, methane produced by reaction of hydrogen with steel in a metal hydride system preferably operated above 350° C. is removed downstream of the Mg-based hydride storage unit using an adsorption cartridge, preferably containing activated carbon.
