Preferred Label : electrode current density;
Detailed label : electrode current density, j;
IUPAC definition : If the charging current is negligible, in the case of a single electrode reaction,
the electrode current density (c.d.) of the electric current flowing through the electrode
is related to the flux density of a species strong B /strong by the equation: \[j
n\ \nu _{{B}} {-1}\ F\ \left(N_{{B}}\right)_{e}\] where (NB)e is the normal component
of the vector NB at the electrode-solution interface, n is the charge number of the
electrode reaction and νB is the stoichiometric number of species strong B /strong
. The ratio n/νB is to be taken as positive if the species strong B /strong is consumed
in a cathodic reaction or produced in an anodic reaction. Otherwise it is to be taken
as negative. With the convention that the normal distance vector points into the electrolytic
solution, a cathodic current is then negative, an anodic current positive.;
