The present paper discusses the validity of experimental apparatus for measuring the effective thermal conductivity of metal hydride by the steady heat flow method. We measured the thermal conductivity of Polyacetal whose thermal property is already known to confirm the validity of experimental apparatus. The average value of experimental results is 0.31 W/m-K. The difference between this value and the literature data of 0.23 W/m-K is 10^<-2> order, so that the measuring accuracy of experimental apparatus is sufficiently high. The reproducibility of experimental results is sufficient since the maximum difference among the experimental results is only 0.06 W/m-K under the same condition. The results obtained in our experiments indicated that the experimental apparatus is reliable as the measurement apparatus of effective thermal conductivity of metal hydride.
