Write the cathodic and anodic cell reactions of a Hydrogen-Oxygen fuel cell.

Open in App

Solution

The reaction occurs at cathode of the cell is $O_{2} (g) + 2 H_{2} O (l) + 4 e^{-} \to 4 O H^{-} (a q)$ . Oxygen is reduced to hydroxide ions. The reaction occurs at anode of the cell is $2 H_{2} (g) + 4 O H^{-} (a q) \to 4 H_{2} O (l) + 4 e^{-}$ . Hydrogen gas is oxidised to water.

Write the cathodic and anodic cell reactions of a Hydrogen-Oxygen fuel cell.

The reaction occurs at cathode of the cell is O2(g)+2H2O(l)+4e−→4OH−(aq). Oxygen is reduced to hydroxide ions. The reaction occurs at anode of the cell is 2H2(g)+4OH−(aq)→4H2O(l)+4e−. Hydrogen gas is oxidised to water.
