Abstract: The thermal transport properties of Ti1.1CrMn powder were determined. This metal hydride shows promise for use in hydrogen storage applications due to its excellent cold-start properties. The thermal conductivity, thermal diffusivity, and specific heat of oxidized and activated powder samples of this metal hydride were determined using the transient plane source technique in a high pressure vessel. It was found that the effective thermal conductivity of the samples showed a strong dependence on hydrogen pressure and particle size, while the thermal diffusivity and specific heat depended on the reaction progress of the oxidation of the metal hydride due to the change in its lattice structure between the desorbed and absorbed phases.
