The Reference Electrode node is a point feature applicable to electrolyte domains (in all the Electrochemistry interfaces). It defines a global electric reference potential
ϕs,ref (SI unit: V) according to
Equation 4-19. The
ϕs,ref can be used in the Electrode Potential feature for setting the electric potential of an electrode boundary with respect to the reference potential. The variable
Evs ref (SI unit: V), according to
Equation 4-20, is also defined in all electrode domains.
The Electric Reference Potential node is a point feature applicable to electrode domains (in all the Electrochemistry interfaces). It defines a global electric reference potential
ϕs,ref (SI unit: V) equal to the dependent variable
ϕs (SI unit: V) in the point. The
ϕs,ref can be used in the Electrode Potential feature for setting the electric potential of an electrode boundary with respect to the reference potential.
Whenever a ϕs,ref is defined, the variable
Evs ref (SI unit: V), according to
Equation 4-20, is also defined in all electrode domains.
The Electrode Potential is a boundary condition feature, applicable to external boundaries of electrode domains (in all the Electrochemistry interfaces). It sets a boundary condition for the electric potential with respect to a defined reference potential according to
Equation 4-21. Electric potentials defined by the Electric Reference Potential and Reference Electrode point feature can be used as input when specifying the Electrode Potential feature.
The variable Evs ref (SI unit: V), according to
Equation 4-20, is also defined on these features.
