Electrochemical pulse and time-lag techniques were used to study the diffusion of H at low concentrations and temperatures of 0 to 60C. For Ag contents ranging from 0 to 50%, the compositional dependences of the diffusion parameters were given by:

log [Do (cm2/s)] = -2.409-x

E (kcal/mol) = 5750 - 5285x + 19100x2

where x was wt%Ag/100.
