Abstract
The variation of overpotential with time on iron membranes cathodically polarised in M/3 sulphuric acid has been found to be due to the formation of an adsorbed layer of hydrogen. This layer decays with time but it can be removed by the application of an alternating current.
Anomalous time-lag curves, permeation maxima and the formation of ‘barriers’ in the course of diffusion of electrolytic hydrogen reported in the literature can be largely attributed to the surface adsorbed hydrogen.
Hydrogen concentrations determined from diffusivity and permeation values are presented together with an experimental methodfor the determination of hydrogen retained in traps.
