Abstract: In this article, the thermal properties and characteristics of a metal hydride alloy in a high hydrogen pressure environment were determined. An instrument was used to determine the thermal conductivity, thermal diffusivity, and specific heat of oxidized and activated Ti1.1CrMn powder under high hydrogen pressures. In doing so, the thermal conductivity of the oxidized powder increased from 0.80 W/m∙K to 1.6 W/m∙K, with increasing hydrogen pressure (from vacuum to 275 bar). The thermal conductivity of the activated powder also increased from 0.31 to 0.71 W/m∙K when the hydrogen pressure was increased from 2.9 to 253 bar.
