Which one of the following cells can convert chemical energy of \(\mathrm{H}_{2}\) and \(\mathrm{O}_{2}\) directly into electrical energy?
1 Mercury cell
2 Daniell cell
3 Fuel cell
4 Lead storage cell
Explanation:
In fuel cell, the energy produced by the combustion of fuels like \(\mathrm{H}_{2}, \mathrm{O}_{2}, \mathrm{CH}_{4}\), etc, is, converted into electric energy e.g., \(\mathrm{H}_{2}-\mathrm{O}_{2}\) fuel cell

Assertion : \(\mathrm{H}_{2}-\mathrm{O}_{2}\) fuel cell gives a constant voltage throughout its life. Reason : In this fuel cell, \(\mathrm{H}_{2}\) reacts with \(\mathrm{OH}^{-}\) ions yet the overall concentration of \(\mathrm{OH}^{-}\)ions does not change.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Fuel cells maintain continuous and controlled flows of hydrogen and oxygen to the electrodes, facilitating electrochemical reactions for steady electrical energy generation, ensuring efficient reactant utilization, minimizing waste, and enhancing reliability in various applications. So, option (2) is correct.
