UDF for current density in PEM fuel cell
 

I am facing a problem of how to make a UDF that calculates current densities in each and every cell of the catalyst layer (varaition is based on the variation in concentration of hydrogen over the catalyst layer)and final give an output in the form of polarization curve.

Hi sajjad
I modeled a PEM in Gambit but when I try to iterate ,I recieve an error would you mind help me?
can I send you my file and you check it?

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
