Dear Researchers :
When I want to solve for the :
- Mole Fraction, H2
- Mole Fraction, O2
- Mole Fraction, H2O
For my water PEM electrolyser, I can't get a solution which makes sense.
But now I can get the solution for the "Electrode Potential with Respecto to Ground" and the "Electrolyte Potential".
The only physics module I'm using is the "Water Electrolyzer" physics, on the mode of PEM water electrolyzer
Can somebody help me ?
Thanks very much sirs.
Hi Franklin. To reiterate my answer in your previous question - I am not sure if you have set enough boundaries in your module. You will have to add membrane, GDLs separately in addition to the Electrolyte phase, electronic conducting phase and H2, O2 gas phase. Furthermore, you have to add electric ground and electrode current in the electronic conducting phase 1 module. Please check the COMSOL application library for PEM Fuel cell modeling, and you can similarly run for the electrolyzer.
