Hello,
I'm going to model the cathode side (Pt/C) of an alkaline fuel cell. To use Tafel equation for obtaining Oxygen reduction reaction kinetic, I need to know the exchange current density (j0,a). This variable depends on the operating temperature of the cell and is defined as the exponential function of temperature. however, I found different values for jref0,a in the literature which are somehow in contradiction and brought some of those below. I'm wondering what's the best reference to obtain this value and how this parameter depends on cell characteristics?
Thanks
