Consider a cell in which the current is activation -controlled. Show that the current for maximum power

Question:

Consider a cell in which the current is activation -controlled. Show that the current for maximum power can be estimated by plotting 10g (I/Io) and Cl - c21against I (where 10=A2joj~ and Cl and c2 are constants), and looking for the point of intersection of the curves. Carry through this analysis for the cell in Problem 25.16 ignoring all concentration over potentials
