Abstract

Hydrogen charging and discharging processes, the diffusion and electromigration were studied in a Pd50Cu5o alloy. These properties are extremely sensitive to the structure. The resistivity increment caused by one atomic percent of hydrogen was measured on the base of Faraday's law, and afterwards used for the determination of the H content in the sample: Δϱ/Δc = 1.45 ± 0.1 μΩcm/at% H/M. At room temperature this alloy looses its hydrogen content in some hours. The beginning of the H ion diffusion starts below room temperature. The small but detectable electromigration shows that the migrating H ions possess a positive electrical charge.
