Turning Chemistry into Electricity

Batteries and fuel cells are devices that convert chemical energy into electrical energy using redox reactions.

• Batteries store energy for later use (like in your phone).
• Fuel cells generate electricity as long as fuel is supplied (like hydrogen-powered cars).

How It Works

In both, electrons flow from one material to another through a wire, creating electricity. Inside, chemical reactions are happening at the electrodes.

Everyday Impact

• Powering electronics and electric vehicles
• Providing backup energy during power outages
