Question

The standard cell potential ( $\mathrm{E}_{\text {cell }}^{\ominus}$ ) of a fuel cell based on the oxidation of methanol in air that has been used to power television relay station is measured as 1.21 V . The standard half cell reduction potential for $\mathrm{O}_2\left(\mathrm{E}_{\mathrm{O}_2 / \mathrm{H}_2 \mathrm{O}}^{\circ}\right)$ is 1.229 V . Choose the correct statement:

Select the correct option:

Oxygen is formed at the anode

The standard half cell reduction potential for the reduction of $\mathrm{CO}_2\left(\mathrm{E}_{\mathrm{CO}_2 / \mathrm{CH}_3 \mathrm{OH}}^{\circ}\right)$ is 19 mV

Reduction of methanol takes place at the cathode.

Reactants are fed at one go to each electrode
