The heats of transport of D and H were determined, at temperatures of between 200 and 250C, by using steady-state methods. The D and H contents ranged up to gas/metal atomic ratios of 0.55. The heat of transport of H at 500K was equal to 0.022eV, while the heat of transport for D was equal to 0.076eV. It was proposed that an intrinsic thermotransport mechanism played a predominant role.
