$\text{P}\text{t}\left|{\text{H}}_2\right|{\text{H}}^{+}\left|{\text{H}}_2\right|\text{P}\text{t}$

Both the electrodes share the same$\left[{\text{H}}^{+}\right].$

$\text{A}:{\text{H}}_2\to 2{\text{H}}^{+}+2{\text{e}}^{-}$



Applying Nernst equation

${\text{E}}_{\text{c}\text{e}\text{l}\text{l}}=0-\frac{\text{R}\text{T}}{2\text{F}}\mathcal{\text{l}}\text{n}\frac{{\text{P}}_{{\text{H}}_{2_{\text{c}}}}}{{\text{P}}_{{\text{H}}_{2_{\text{a}}}}}$

$=\frac{-\text{R}\text{T}}{2\text{F}}\mathcal{\text{l}}\text{n}\frac{{\text{P}}_2}{{\text{P}}_1}=\frac{\text{R}\text{T}}{2\text{F}}\mathcal{\text{l}}\text{n}\frac{{\text{P}}_1}{{\text{P}}_2}$
