The reaction in the given concetration cell is

\begin{matrix} H_2&+ & 2H^+\rightarrow 2H^+&+ &H_2 \\ (LHS) & &&& (RHS) \end{matrix}

\begin{array}{l}{\therefore \text { From the Nernst equation,}} \\\\ {\qquad \begin{aligned} E_{\text {cell }} &=\frac{0.059}{2} \log \frac{P_{\mathrm{H}_{2}(\mathrm{L} . \mathrm{H} . \mathrm{S} .)}}{P_{\mathrm{H}_{2}(\mathrm{RH} . \mathrm{S} .)}} \\ &=\frac{0.059}{2} \log \frac{2}{10}=-0.0206 \mathrm{\: V} \end{aligned}}\end{array}
