A new composition material for metal-hydrogen, which can store hydrogen, has been developed to increase amount of hydrogen absorption. Thermal diffusivity and conductivity for the new composition material are required to design a storage tank with the metal-hydrogen. For the metal-hydrogen called as AB_5, themal diffusivity and conductivity are measured by using a method newly developed based on an inverse solution for one dimensional heat conduction. It reveals that the thermal diffusivity, a, is almost constant value of 4.0×10^<-7>m/s^2 in a range of 10 to 30℃ and of 0.148 to 0.502MPa, while the thermal conductivity linearly increases from 1.0 to 3.0W/(mK) for the different temperature with the pressure and the composition rate.
