problem with PEM fuel cell modeling and I-V curve

problem with PEM fuel cell modeling and I-V curve

problem with PEM fuel cell modeling and I-V curve

(OP)
I've been recently working on PEM fuel cells , and modeled a 3D single PEM in gambit. I wanted to compare my information & model with an article
therefore I used the same parameters in the article and there's no problem running the program based on the article, except that there are some
differences between my results and the one in the article. as you know we have 3 different voltage drop in fuel cell , 1. concentration 2.activation 3.ohmic. I think the I-V polarization curve which Fluent6.3 gives me, only considers ohmic as a voltage drop ( Please note that you should give the "V" factor to the program & it would provide you with the "I' factor) What I'm looking for is the answer to the question that whether the program considers the other two voltage drops or not? Is there an option provided in the program to active considering the other factors as well?If yes where exactly this option can be activated? if no, what is the origin of the problem?


Also, I wanted to make sure if the current density that I get in each program run for each voltage is the same number as the Fluent shows in continuities when running?


and my last question is that are there any commands in the Fluent that gives us the IV polarization curve automatically so that we don't have to run it for each individual voltage? I've read somewhere that we can use "SSV" & "SSC" commands for this but I couldn't make it work.
