Hydrogen Fuel CellsThe Future of Energy

What is a Hydrogen Fuel Cell?A hydrogen fuel cell is a electrochemical conversion device,

which means that it uses chemicals to generate electricityThe most common chemicals in fuel cells are hydrogen and

oxygenFuel cells are a very clean form of energy because in a

hydrogen fuel the only byproducts are water and electricityFuel cells have a wide variety uses (see next slide)Hydrogen is the most plentiful element in the universeHydrogen has the highest energy content per unit weight

of all fuels, 52,000 btu/lb, over three times that of gasoline

The uses of Fuel CellsAutomobiles

Processors

Power Plants

How does a Hydrogen Fuel Cell work?A hydrogen fuel cell works by fusing together hydrogen

and oxygen to form waterHydrogen is stored compressed in a liquid formThe fusion of the atoms produces an electrical chargeThe charge is then collected by two conductor platesThe electricity is then routed to either a battery for storage

or a motor to power a car (see diagram on next slide)
