At first, in order to measure the effective thermal conductivity of MH bed, we proposed simple unsteady state method. In our measurement, the effective thermal conductivity of MH alloy bed is extremely low (under 1 W/m ・ K). And, the effective thermal conductivity of MH-2 bed is higher than that of MH-1 bed. Next, an attempt by mixing the carbon fiber into the MH bed is discussed, to enhance the heat transfer performance. The experimental parameters of heat transfer enhancement are the length and mass fraction of carbon fiber. As the best result of MH bed, the effective thermal conductivity of mixing 2-3 wt.% carbon fiber is three-four times larger than that of the pure MH bed.
