Yes Of Course.......!!!
garvtrpt:
ok
let me post it
The theoretical voltage of a fuel cell is 1.23 V
Q.1- If the operating point of fuel cell is 0.6V, Find the Overpotential losses?
Q.2- If the impedence (ohmic) due to the membrane and contact resistance of the cell is 0.01 ohm and the current in the cell is 15 Amps. Find the polarization losses due to reasons other than ohmic loss?

Answer:
Polarization losses can be due;
1) heat loss by conduction, convection, radiation and diffusion,
2) Impedence mis-match can cause serious losses in the electrical circuit
3) Major loss is accounted for by ohmic resister losses that are inevitable
