The behavior of H in PdH0.1, Pd77Ag23H0.1 and Pd50Ag50H0.1 was monitored by means of resistometry. It was known that H migrated towards the cathode at 300 to 473K in the PdH0.1 and Pd77Ag23H0.1 systems. In the case of Pd50Ag50H0.1, H migrated towards the cathode below 400K, but towards the anode at higher temperatures. Its effective valency increased with temperature. The activation energies for H diffusion were equal to 0.23eV for PdH0.1, 0.221eV for Pd77Ag23H0.1 and 0.31eV for Pd50Ag50H0.1.
