Which of the following statements is NOT correct for $\mathrm{H}_2-\mathrm{O}_2$ fuel cell?
Which of the following statements is NOT correct for $\mathrm{H}_2-\mathrm{O}_2$ fuel cell?
$\mathrm{H}_{2(\mathrm{~g})}$ serves as fuel
$\mathrm{O}_{2(\mathrm{~g})}$ is an oxidising agent
Platinum wires are used as anode and cathode
Hot aqueous KOH solution acts as an electrolyte
Solution
In an \(\mathrm{H}_2-\mathrm{O}_2\) fuel cell, the electrodes are typically porous carbon electrodes impregnated with catalysts like platinum, palladium, or nickel to facilitate the reactions.
The use of platinum wires as electrodes is not standard practice because:
Platinum is expensive, and using it as solid wires would not be cost-effective.
Porous electrodes increase the surface area for the reaction and improve efficiency.
Conclusion: This statement is NOT correct.
