How to create a No Flux Boundary condition for one of two chemical species

Please login with a confirmed email address before reporting spam

I'm am modeling a fuel cell using transport of concentrated species (tcs) with 2 species, wH2 and wH2O. In the fuel cell there is a boundary where the water (wH2O) is able to pass through but the hydrogen (wH2) cannot.

Is there a way to create a no flux condition for only 1 species, so that the water can freely move through the boundary but the hydrogen cannot?

I would like to eventually expand this to include a total of 4 species, where water is the only species that can move freely throughout the entire fuel cell.

Hello,

Did you manage to solve this problem... I am looking for something very similar, where only one species should crossover through the membrane.
