How To - Understand Hydrogen Cars

Toyota and Honda will introduce Hydrogen Cars in 2015. Here's how they work..

A hydrogen car is a 100% electric car, but instead of a battery it uses hydrogen fuel cells. These are simple, feed them hydrogen gas and they will constantly generate electricity. They are like a battery that never need recharging. There is no combustion, hydrogen gas is simply fed to the fuel cells to produce electricity.

So where do we get the hydrogen? The cars carry high pressure tanks of hydrogen to supply their fuel cells. The tanks get refilled at a hydrogen gas station, and the filling process is very similar to regular gas filling. The hydrogen gas station produces its hydrogen on the spot. How? By electrolysis of water.

Yes, the raw material to generate hydrogen gas is water!

So, the hydrogen gas station makes hydrogen from water. Cars refill their hydrogen tanks. The hydrogen goes through the car's fuel cells to generate the electricity that drives the car. And the exhaust? The car's exhaust is water vapor! Zero pollution.

The whole thing is a water to water cycle!

The range of a hydrogen car is about the same as a gasoline car, and the refueling time is about the same.

Also, hydrogen is the most abundant element in the universe. So I doubt we'll run out!
