Q1

The standard cell potential \(\left({\mathrm{E}}_{\text{cell }}^{⊖}\right)\) of a fuel cell based on the oxidation of methanol in air that has been used to power television relay station is measured as \(1.21V\) . The standard half cell reduction potential for \({\mathrm{O}}_{2}\left({\mathrm{E}}_{{\mathrm{O}}_{2}/{\mathrm{H}}_{2}\mathrm{O}}^{\mathrm{O}}\right)\) is \(1.229V\).Choose the correct statement:
