Question

Define Fuel cell

Hint:

Fuel cells are environmentally friendly because their only byproduct is usually water, making them an important alternative to traditional power sources.

Answer 1

A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (such as hydrogen or methanol) into electrical energy through a redox reaction. The reactants are continuously supplied to the cell, and the products are continuously removed. The most common example is the hydrogen fuel cell, where hydrogen reacts with oxygen to produce water and electricity.
