Hello, I am using the addon model 4, unresolved SOFC model and I enable the CO electrochemistry, I assume that the current is allocated between H2 and CO, the total current is I_tot, and current for H2 is α*I_tot，current for CO is (1-α)*I_tot

actually i want to define my own current split factor of alpha; and I wonder that when calculating the activation overpotential of the cell using H2-H2O, it is using I_tot or α*I_tot？as I do not see a notification in the constit.c document when calculating activation overpotential;

Hello Jingjing,

Here how you can edit the split factor

When CO is not present, then \alpha is not needed, or you can think \alpha is 1.0

Best,

John
