Hi,
I am using COMSOL 5.4 and I met a problem in Electroanalysis module. The result I try to get is the cyclic voltammogram of a one electron transfer irrversible electrochemical reaction. The module supplied several choices in Electrode reaction e.g. Bulter-volmer, linear Bulter-volmer, Anode Tefal. I was using electroanalysis Bulter-volmer for reversible or quasi-reversible electrochemical reaction. However, this time I have a irreversible electrechemical reaction to simulate. I have just no idea which module I should use. I have tried other modules and it looks like no one is correct for the current situation.
Also, I could give a small rate constant to get a similar cyclic voltammetry respone. However, when the potential range is bigger, I could still see a reductive current in CV, which should not be there for an irreversible electrochemical reaction in cyclic voltammograms.
