Fuel Cells: Clean Energy Through Physics

Fuel cells generate electricity by combining hydrogen and oxygen.
The main byproducts are heat and pure water—no harmful emissions.
Inside, an anode, cathode, and electrolyte drive the reaction.
Hydrogen atoms split into protons and electrons at the anode.
Electrons flow through a circuit, creating usable electric power.
Proton Exchange Membrane (PEM) fuel cells are common in vehicles.
Fuel cells are highly efficient, converting chemical energy directly to electricity.
They can power cars, buses, buildings, and even space missions.
NASA has used fuel cells since the Gemini and Apollo programs.
They showcase physics and chemistry working together for clean energy.
