Default Fuel Cell modeling
Posts: n/a
Hi, everybody,

I am modeling PEMFC. Now I run in troubles and I expect I can get a favor from you. I use UDS to describe electron potential and proton potential but I do not know how to set boundary conditions for them. Firstly, I give my process for electron potential. In define_diffusivity I give the conductivities of catalyst layer and diffusion layer(electrode) and set conductivitities of membrane zero (the number is only for UDS_electron potential). Then I give the boundaries conditions: the interface between anode diffusion layer and channel is 0 and the interface between cathode diffusion layer and channel is 1V. However, the UDS can not be run. What's wrong with the idea? what need I do for the model? How do I deal with the UDS_electron potential and UDS_proton potential? Thank you very much!
