| Research Abstract |
The low heat conductivity of the packed bed is a key issue inthermal engineering fields. It is also one of the dominant factors behind realizing a fuel cell vehicle society because it prevents quick recharging of hydrogen due to its exothermic reaction. In this study, we examined the enhancement in the effective thermal conductivity of the packed bed with the use of single-walled carbon nanotubes, which were directly synthesized on the particles of the packed bed (aluminum oxide). Consequently, growing single-walled carbon nanotubes of 7 vol.% to the void space of the packed bed enhanced the effective thermal conductivity by three times.
