Question:
In fuel cell ___ are used as catalysts.
In fuel cell ___ are used as catalysts.
Updated On: Apr 20, 2024
- Zinc - Mercury
- Platinum - Palladium
- Lead - Manganese
- Nickel - Cadmium
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Fuel cells are electrochemical devices that convert the chemical energy of a fuel, such as hydrogen, into electrical energy through an oxidation-reduction (redox) reaction.
Catalysts are used to facilitate the redox reactions occurring at the electrodes of the fuel cell. Platinum and palladium are commonly used as catalysts in fuel cells due to their high catalytic activity, stability, and resistance to corrosion.
Therefore, the correct answer is (B) Platinum - Palladium.
