I WONDER - How Can Hydrogen Produce Electricity?

Hydrogen fuel cells generate electricity through a chemical reaction between hydrogen and oxygen, producing only water and heat as byproducts, making them environmentally friendly. Unlike fossil fuels, they do not emit harmful substances like carbon dioxide, thus not contributing to climate change.

What device is used to generate electricity from hydrogen?

• Battery

• Solar panel

• Wind turbine

• Fuel cell

What are the byproducts of the chemical reaction in a hydrogen fuel cell?

• Carbon dioxide and heat

• Water and heat

• Methane and water

• Oxygen and carbon dioxide

How does the emission from hydrogen fuel cells differ from fossil fuels?

• Fossil fuels release water and heat

• Hydrogen fuel cells release carbon dioxide

• Fossil fuels release only oxygen

• Hydrogen fuel cells release no harmful substances

Which of the following is a harmful emission from burning fossil fuels?

• Oxygen

• Carbon dioxide

• Heat

• Water

What environmental issue is exacerbated by burning fossil fuels?

• Deforestation

• Water pollution

• Climate change

• Soil erosion
