Hydrogen half cell equation
WebReduced: A compound/element gaining electrons. For hydrogen fuel cells we know that we use hydrogen and oxygen, therefore were going to be using the half equation for oxygen and the half equation for hydrogen. The half equation for hydrogen is: 2 H 2 ( g) + 4 O H − ( a q) → 4 H 2 O ( l) + 4 e −. The half equation for oxygen is: WebElectrolysis of aqueous solutions. At the negative electrode (cathode), when the metal is more reactive than hydrogen, hydrogen is discharged and the half equation is: 2H+ + …
