Hydrogen Cars - Explained in 90 Seconds
Hydrogen cars are very different from all other cars (gasoline, battery, hybrid). 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 generate electricity. They are like a battery that never need recharging. There is no combustion, nothing burns, 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 gas to supply their fuel cells. The tanks get refilled at a hydrogen gas station, and the filling process is very similar to regular gasoline 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 and generates electricity to drive the car. And the exhaust? The car's exhaust is water vapor. There is 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!
