To find potential formula is
Ecell = E° −  0.0591 log [H₂]
                        1         [H⁺]

⇒ for  [H⁺]                          
pH = 10 so,                           or  [H⁺] = 10∧⁻pH
pH = − log [H⁺]                            pH = 10  
so [H⁺] = 10⁻¹⁰                            [H⁺] = 10⁻¹⁰ 

⇒ E° = 0

⇒ [H₂] = 1 [1 atm]

Ecell = E° −  0.0591 log [H₂]
                        1         [H⁺]
        = 0 −  0.0591 log   [1]  
                      1         [10⁻¹⁰ ]
        = −  0.0591 (log 10¹⁰)
        = −  0.0591 (10 log 10)
        = −  0.0591 (10 * 1)      {log 10 =1}
        = −  0.0591 x 10 
Ecell = − 0.59 V
