Hydrogen has known rich resource and it has the biggest of explosion power in the earth. Then, hydrogen energy applications have recognized clean materials and high energy carrier. So, Hydrogen energy apply for fuel cell by Magnesium and Magnesium-based alloys. Magnesium and Magnesium-based materials are a lightweight and low cost materials with high hydrogen storage capacity. However, commercial applications of Magnesium hydride are currently hinder by its high absorption/desorption temperature, and very slow reaction kinetics. Therefore, one of the most methods to improve kinetics focus on additional transition metal oxide. Addition to transition metal oxide in MgHx powder produce MgHx-metal oxide composition by mechanical alloy and it analyze XRD, EDS, TG/DSC, SEM, BET and PCT. In this research consider kinetics by transition metal oxide rate and Hydrogen pressure and we can see behavior of absorption profiles by addition catalyst(transition metal oxide) |
