Abstract: ABSTRACT “Electrochemical Permeation Method and System for Identifying Artefacts in Hydrogen Diffusion Measurement” The present invention relates to an electrochemical permeation method and system (100) for identifying artefacts in hydrogen diffusion measurement. The proposed method includes positioning the at least one steel specimen (101c) between at least one hydrogen-charging chamber (101a) and at least one hydrogen-detection chamber (101b) of an electrochemical permeation cell (101) such that the steel specimen (101c) forms a common working electrode of the chambers, applying, using at least one potentiostat (102) electrically coupled to the electrochemical permeation cell (101), a galvanostatic hydrogen-charging current density to a hydrogen charging side of the steel specimen (101c) and an anodic potential to a hydrogen-detection side of the steel specimen (101c), recording a hydrogen charging potential and a hydrogen-oxidation current density as functions of time to obtain a first rise transient, discontinuing the galvanostatic hydrogen charging current density and recording the hydrogen-oxidation current density as a function of time to obtain a first decay transient.
