  • System for purifying hydrogen from a metal hydride storage system
    Patent number: 9878279
    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.
    Type: Grant
    Filed: April 30, 2016
    Date of Patent: January 30, 2018
    Assignee: L'AIR LIQUIDE SOCIÉTÉ ANONYME POUR L'ÉTUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE
