Fuel Cells

Imagine a car racing down the road, emitting nothing from its tail pipe but pure water. That car would be powered by a hydrogen fuel cell.

What's more, fuel cells are funny. Or at least they are in this first video. Once you've watched it, check out the other resources (particularly "The Artificial Leaf"), and see how far these amazing devices have come since that video was made.

Just Add Water

Just Add Water

Every water molecule has two atoms of hydrogen, but how do you get that hydrogen alone, so you can use it in, say, a fuel cell? One way is to use particles of aluminum barely larger than atoms. More...

Fuel Cell

Fuel cells use their fuel more efficiently than internal combustion engines and have no moving parts. If their fuel is pure hydrogen, they emit nothing but heat and water (which you can drink). More...

Fuel Cells: Fueling the Future

Running electricity through water splits it into hydrogen and oxygen. A scientist in 1839 wondered if this process, called electrolysis, could be reversed. The result was the fuel cell. More...

Hydrogen Basics

Hydrogen Basics

Hydrogen is the most abundant element in the universe. But it's also the lightest, so the only way it exists on Earth is if it's bound up with something else. For more hydrogen facts, click here. More...

The Artificial Leaf

Solar power is great, until night falls. But now an MIT scientist has figured out how to store the Sun's energy. How? By getting hydrogen from water — in other words, by imitating the leaf. More...
