Show Solution
The Correct Option is C
Solution and Explanation
The question asks about a device that converts the energy from the combustion of fuels like hydrogen and methane directly into electrical energy. To address this question, let's examine each option:
- Dynamo: A dynamo is a device that converts mechanical energy into electrical energy. It relies on the principle of electromagnetic induction and is not directly related to the combustion of fuels.
- Ni-Cd Cell: This is a type of rechargeable battery (nickel-cadmium battery) which stores electrical energy but does not involve combustion in its operation or generation of energy.
- Fuel Cell: A fuel cell is a device that converts the chemical energy of fuels (like hydrogen and methane) into electrical energy through a chemical reaction with oxygen or another oxidizing agent. This conversion occurs without combustion and is therefore the correct answer.
- Electrolytic Cell: This device is used to drive non-spontaneous chemical reactions using electrical energy. It doesn't directly convert combustion energy to electrical energy.
From the above analysis, the device that fits the required definition of converting energy of combustion directly into electrical energy is the Fuel Cell.
Conclusion: The correct answer is a Fuel Cell, which directly converts chemical energy into electrical energy without combustion.
