Question:medium
Which of the following cell converts the energy of combustion of fuel into electrical energy?
Which of the following cell converts the energy of combustion of fuel into electrical energy?
Show Hint
Fuel cells are distinct because they convert the energy of combustion directly into electrical energy without needing an external circuit for combustion.
Updated On: Feb 24, 2026
- Mercury cell
- Fuel cell
- Dry cell
- Lead storage cell
Show Solution
The Correct Option is B
Solution and Explanation
An electrochemical reaction within a fuel cell directly transforms fuel's chemical energy into electrical energy. This process involves the combustion of fuel, like hydrogen, at electrodes, thereby generating electricity. Unlike fuel cells, mercury, dry, and lead storage batteries utilize distinct electrochemical mechanisms.
