Question

Define fuel cell. Give two advantages of fuel cell over ordinary cell.

Hint:

Fuel cells are more efficient and environmentally friendly than traditional batteries, making them ideal for sustainable energy solutions.

Answer 1

A fuel cell is a device that converts chemical energy from a fuel into electrical energy through an electrochemical reaction. Unlike a battery, which stores energy, a fuel cell continuously generates electricity as long as fuel is supplied.
Two advantages of fuel cells over ordinary cells are: 1. Fuel cells have a higher efficiency since they directly convert chemical energy to electrical energy without intermediate steps.
2. Fuel cells produce fewer pollutants compared to traditional cells, which may generate heat and waste.
