hi, im currently doing a simulation of pem fuel cell using ansys fluent. can anyone here explain to me what is the significance of I-V polarization curve to the efficiency of the fuel cell



thanks in advance!

Hi, actually I'm trying to using ANSYS 14.0 to analysis PEM fuel cell, could you tell my how can I do it

The way the IV curve gives you some idea of the efficiency is that a theoretically 100% efficient cell would have a perfectly flat horizontal IV 'curve' which means that the voltage would not drop with increasing current. The flatter/higher your curve, the better.
