Hi,

I am modelling soec using module 3 fuel cell and electrolysis, using electrolysis option. from the manual, the steam is provided at the anode (fuel electrode), and air is at the cathode, may I know how should I set up the voltage, let say the cell voltage is at constant voltage is 1.3V, should I set up is 0V at the anode and 1.3V at the cathode as per manual? or the other way around?

I found this in the manual, and a bit confused on setting up the voltage for the electrolysis mode for soec.

Note that, conventionally, the negative voltage is supplied to the cathode side in power consuming devices such as electrolyzers. ANSYS Fluent adopts the inverse notation where the negative voltage is supplied to the anode side whilst cathode remains positively charged. The main reason for this discrepancy is that the same infrastructure is used for both the electrolysis and fuel cells models. Usage of the terms "anode" and "cathode" in this manual and in the user interface should be interpreted according to conventions for power-supplying devices.

The model seems to work when I put -1.3V at the anode sides, may I know if this is right?

Thank you!
