Fuel Cell, Etn, Er and polarizations

[4220Fox]

Can anyone help me explain the elements of the fuel cell polarization curve. Please be sure to include Etn, Er, and the various polarizations. I am interested by the use of thermodynamics as well... Thank you-

Hi All in the community!

Any ideas on the elements of the fuel cell polarization curve? Thank you,

OK - How about some basics on the Etn, Er and the various polarizations WRT fuel cells? Thank you,
