Fuel Cell model
 

Hello guys,

I've been building my fuel cell UDF model over one year and I an almost there. The only remaining issue I can see is that the difference of the molar concentration in the inlet and outlet is very small (~1kmol/m3) while I am expecting something like 35kmol/m3 at the inlet and 17kmol/m3 at the outlet.

Does anyone created its own fuel cell model using UDF before? Any hints that could help me solving this issue?

In my mesh I assumed that the flow channel, catalyst layer and gas diffusion layer as fluids (3 different threads). I do not know if it could be related with the mesh, but if you think so, any advice would be great.

Thanks all in advanced.
