mean catalytic activity rate, Math - eimean exchange current density
mean current density
Defined as
Math - e
where Math - symbol is the electric current and Math - symbol is usually taken as the geometric area of the electrode. However the nature of the area used in this calculation must be clearly stated. In interpreting the mean current density it is important to know whether the current is uniformly distributed over the electrode interface.
