How do the ions transfer between solutions in an electrochemical cell?

Given the data at $25\, ^oC$:
$Ag + I^{-} \rightarrow AgI + e^-$,$E^o = 0.152\, V$
$Ag \rightarrow Ag^{+} + e^-$,$E^o = -0.800\, V$
What is the value of $\log K_{sp}$ for $AgI$? $(2.303\, RT/F = 0.059\, V)$

For the cell reaction,$Zn + Cu^{2+} \to Zn^{2+} + Cu,$ the cell representation is:

Give the types and examples of electrodes.

From a solution of $CuSO_4$,the metal used to recover copper is

What advantage do the fuel cells have over primary and secondary batteries?
