Record 1 2011-02-11

English

Subject field(s)
  • Electrochemistry
DEF

Defined by the equation: [delta] = D/kd = nFDcA/Ii where D is the diffusion coefficient, kd is the heterogeneous diffusion rate constant, F is the Faraday constant, c is the concentration, A is the geometric area of the electrode, Ii is the limiting current and n is the charge number of the cell reaction.

OBS

The word "delta" must be replaced by the corresponding Greek letter.

DEF

Définie par l'équation : [delta] = D/kd = nFDcA/Ii où D est le coefficient de diffusion, kd est la constante de vitesse de la diffusion hétérogène, F est la constante de Faraday, c est la concentration, A est la surface géométrique de l'électrode, Ii est le courant limite et n est le nombre de charges dans la réaction.

OBS

Le mot «delta» doit être remplacé par la lettre grecque correspondante.

Record 2 1998-02-16

English

Subject field(s)
  • Electrochemistry
OBS

A fictitious layer corresponding to the dotted straight lines of the diagram which shows the concentration profile along the direction perpendicular to an electrode surface. The thickness ... of this layer is called the effective (or equivalent) thickness of the diffusion layer.

French

Domaine(s)
  • Électrochimie
OBS

Une couche fictive qui correspond aux lignes droites pointillées du diagramme qui présente le profil de concentration de long de la direction perpendiculaire à une surface d'électrode. L'épaisseur [...] de cette couche se nomme épaisseur effective (ou équivalente) de la couche de diffusion.
