I am currently trying to study impedance modelling for solid oxide cells, and i am not able to find the equations that are being used for that anywhere in the documentation. Can someone help me with this?

Total current = faradaic current + displacement current Faradaic current = electrode reaction, typically via kinetic expression i.e. Butler-Volmer equation. Displacement current = C·dE/dt

Equations are found below Electrode nodes.
