Ohmic Loss in Fuel Cells

The charge transport across a conductor of cross-sectional area. A, and thickness, L, is given by Ohm s law and Equation 7.6b as 

Integrating Equation 7.56 across a charge conductor of thickness L and cross-sectional area A, we get total voltage drop across the electrolyte or the ohmic loss owing to charge transport as 

Charge transport and ohmic resistance in a charge conductor. 

On the basis of the electrical circuit analogy, we can define the ohmic resistance owing to charge transport through the charge conductor given as 

Another alternative expression of ohmic resistance is given in terms of resistivity (p) as
