What is the energy conversion that occurs during the redox reaction in a Daniell cell?

Identify the anode,cathode,positive electrode,and negative electrode for the $Daniell$ cell $(Zn-Cu)$ and the $Copper-Silver$ $(Cu-Ag)$ cell.

In which cell,construction like a galvanic cell can be observed? Explain.

Give advantages of fuel cell.

The anode half-reaction occurring during the discharge of a lead storage battery is

For a hydrogen-oxygen fuel cell at $1 \text{ atm}$ and $298 \text{ K}$, the reaction is $H_{2(g)} + \frac{1}{2} O_{2(g)} \rightarrow H_{2}O_{(l)}$; $\Delta G^{\circ} = -240 \text{ kJ}$. The $E^{\circ}$ for the cell is approximately (Given $F = 96,500 \text{ C}$): (in $\text{ V}$)
