Default Fuel cell modeling

Is there anyone doing PEM fuel cell modeling with Fluent?

I found there is no way to avoid species crossover through the membrane. Fluent takes the whole domain for computation, and does not allow users to deactivate some regions for a certain governing equations, like what FEMLAB does.

Can someone with experience give me some hint on how to handle this issue?

Your kind help will be appreciated.

Steven

hi, Steven, you can write a udf to define the diffusivity for each species. the diffusivity of hydrogen/oxygen is sevral orders bigger in gas channel than in membrane(electrolyte), so usually they won't penetrate the membrane through this method. I've seen another approach which employed a big source term to freeze the mole fraction to zero in the region where the species actually does not exist. but i never implenment that successufully. good luck.

Hi , I am used the Fluent for Modeling PEMFC but I found the difficulty ;if you can guide me for modeling correct the all phenomena founded in PEMFC.

ALSO CAN ANY ONE SEND ME THE LINK FOR THE FUEL CELL MODULE TUTORIALS. I AM IN GREAT NEED OF THESE TUTORIALS. THANK YOU
