Question

question: what device converts the energy of a chemical reaction directly into electricity? answer options: select one of four thermocouple generator fuel cell thermostat

Explanation:

• A thermocouple converts temperature difference to electricity (based on the Seebeck effect), not chemical energy.
• A generator typically converts mechanical energy to electricity (e.g., in power plants, mechanical energy from turbines is used to generate electricity).
• A fuel cell uses a chemical reaction (between a fuel like hydrogen and an oxidant like oxygen) to directly produce electricity.
• A thermostat is a device used to regulate temperature, not convert chemical energy to electricity.

Answer:

Fuel cell
