This article described an experimental set up using the TPS instrument and a high pressure vessel to enable researchers to accurately measures the thermal conductivity of metal hydrides as a function of pressure. Metal hydrides have promise in applications of hydrogen storage in the auto industry, however a better understanding of their thermal properties is required. The authors investigated thermal conductivity, diffusivity, specific heat and thermal contact resistance. Experimental trials ...
This article is based on research that has been done to improve hydrogen storage systems with on-board reversible metal hydrides. The study involved the compaction of the sodium aluminum hydride particles, as well as the addition of either aluminum or expanded natural graphite (ENG) to the powders to determine how their addition affects the thermal conductivity. It was found that the compaction of the powders improved the volumetric capacity of ...
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 ...
