Abstract: 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 Hot Disk Thermal Constants Analyzer TPS500 measured the thermal conductivity of the SAH pellets with (ENG) worms using the Transient Plane Source (TPS) method. Results showed greater enhancement of thermal conductivity in the perpendicular direction of compaction rather than in the parallel direction.
