In hybrid cars, is hydrogen used as a primary fuel like gasoline or is it used to burn gasoline efficiently?
I skimmed the Wiki hydrogen article this morning and was unable to find out if hydrogen is used as the primary fuel in today’s hybrid hydrogen/gasoline cars or if it is used to burn gasoline more efficiently with less carbon dioxide emissions. Can you answer this for me? Here is the Wiki article: http://en.wikipedia.org/wiki/Hydrogen_car
The hydrogen is used as a fuel in one of two ways, depending on how the engine is constructed.
In the first way, it is burned directly, the same as gasoline.
In the second method, it is broken down in what's called a fuel cell to create electricity, which powers an electric motor to run the car.
Most hybrid cars today don't use hydrogen as a fuel. Their engines run on gasoline for acceleration and on electricity produced by batteries for slow and crusing speeds. The gasoline engine keeps the batteries charged, the same way it charges the battery in conventional cars, so there's no need to "plug in" the car when it isn't in use.
