Add this node to the Electrode Surface Coupling and Porous Electrode Coupling features to define molar fluxes and sources based on electrode current densities in an Electrochemistry interface.

Current densities from Electrode Reaction (iloc, SI unit: A/m2) or Porous Electrode Reaction nodes (iv, SI unit: A/m3) of any Electrochemistry interface in the model are available for selection as the Coupled reaction, and user-defined expressions are also supported.

Enter the Number of participating electrons nm (dimensionless) and the Stoichiometric coefficient vc (dimensionless) as explained in the theory section linked below.
