Thermoelectric power of hydrogenated palladium and some of its dilute alloys, between 80 and 300 K

Influence of hydrogen on electron transport of palladium alloyed with silver

“…For x = 0.14 and 0.23, a flat maximum in the S(T) relationships, localized between 150 and 200 K, appears after a few successive hydrogen desorptions but still within the ␤-phase region. A similar behavior was previously observed in the Pd-H system [5].…”

“…Thermoelectric power, S, and electrical resistance, r, of one-and two-phase samples, as received after hydrogen loading (labeled "1" on figures) and after successive partial hydrogen desorptions (labeled "2", "3", etc), have been measured simultaneously in the temperature range between 80 and 300 K. The lowest hydrogen contents have been achieved by heating the samples up to 340 K. More experimental details can be found in [5] and [8].…”

“…The maximum could be seen in several Pd-rich alloys (up to, at least, 3 or 5 at. % of the second element) as well [5]. In the case of the Pd 1−x Ag x alloys (0.14 ≤ x ≤ 0.39), there is no indication for the existence of the maximum.…”

“…On the other hand, TEP is a physical quantity that is very sensitive to details of 0925-8388/$ -see front matter © 2004 Elsevier B.V. All rights reserved. doi:10.1016/j.jallcom.2004.11.060 the electronic structure -recently, a marked influence of the Ru and Rh solutes on TEP of palladium hydride [5], the analog of silver, was reported. The results have been interpreted in terms of the virtual bound states model.…”

Measurement of hydrogen in alloys by magnetic and electronic techniques

“…The objective of this measurement was to study the effect of absorbed hydrogen on the thermoelectric power as expressed by the Seebeck coefficient [19,20]. The thermopower, an intrinsic property of a material, characterizes the electronic density of states at the Fermi level: the amount of electric charge and the type of charge carrier.…”
