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 ...
Aspects of hydrogen distribution systems need improvement for their applications in fuel cell vehicles. In this paper, chemical and physical characteristics of the H2 storage material, sodium aluminum hydride (SAH), were examined after the samples were compacted and Expanded Natural Graphite (ENG) worms were added. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the SAH pellets with (ENG) worms using the Transient Plane Source (TPS) method. Results showed ...
