3d pemfc model - fluent module & gambit - error
 

I try with fluent pemfc modul and use tutorial ' modeling a single channel , counter flow pem fuel cell . 2007 fluent inc ' but i dont know what the problem is cauz after first iteration the error messge 'floating point error' will appear . I think maybe boundry condition/zones that present in gambit or mesh size are wrong , but i do exactly according to the tutorial .

1- Is anode/cathod side flow channel each one apply 3 faces & and 1face that remine apply with gdl or they have another definition ?

2- Is anode/cathod side diffusion layer each one apply 3 faces or 4 faces or they have another definition ?

example for 4 faces: (2 faces ... interface collector & gdl) (1 face ... interface anode/cathod & gdl) (1 face interface catalyst & gdl)

3- do u have idea , what is my mistake ?

i am thankfull if you have mesh or case file about and send for me .

Hi, I also meet with this problem, the iteration can not continue
I want to know if you have solved this problem.
Could you share, thank you~~

what version do you use?

I'm having exactly the same problem. Did you find a solution to this?
If so, please post it. Thank you.

I am new in Fluent , firstly I was used the code Comsol for modeling the PEMFC but I found the difficulty because my supervisor do not help me so I decided to use the software Fluent but again I found the difficulty, I began by the tutorial of PEM fuel cells 3D but without results, please if you can help me.
Bye with my good wishes

Did you follow step by step the tutorial?
Where is your problem?

plot IV in PEMFC 3D
 

I am solver the pemfc 3d but i want how he plot the curve of polarisation

I'm a new of Fluent modelling PEMFC and I found I encountered the same difficulties. I'm sure you have solved the problem and get many achievments. Can you post how you solve the problem in detail.
Thank you.

please help me if you know
