TRANSCRIPT
Gasoline is made from fossil fuels …mostly oil
Fossil Fuels
Oil pumped from the ground
This type of fuel will notlast forever
So, a new type of fuel needs to be made …
An Alternative Fuel
TOMORROWS ENERGY
HYDROGEN
The most abundant resource in the universe
Hydrogen Atom
H
O
H
Defined: Hydrogen
Electron
An atom that has only one electron
Hydrogen is a gas and when combined with oxygen…
forms waterH2O
Symbol H
HOW DO WE MAKE
HYDROGEN ?
Hydrogen gas can be made from water H20
But , no .. You can’t just put water in your car to make it run.
Electrolysis Sending electricity through water will split the molecules ofwater apart, creating …………Hydrogen Oxygen
Scientific Fact
Electricity is used to split the watermolecule into its separate parts
Now that we have hydrogen
Defined: A fuel -cell is a device that converts this hydrogen into electricity …

SMALL FUEL CELL
Fuel Cell
Hydrogen tanks
Electric Motor
Hydrogen enters the fuel cell to create electricity that drives the electric motor for the wheels.
ELECTRIC MOTOR
HYDROGEN FUEL
SKATEBOARD DESIGN
The electric motor that will be used to drive the car of the future
FUEL CELL CAROnly emissions out the exhaust is water vapor
Future Cars that run on Hydrogen
Example of a fuel-cell car
Hydrogen filling station
HYDROGEN TANK
Under very high
pressure

Toyota Mirai at a hydrogen filling station
In the last few years three automakers--Toyota, Honda, and Hyundai ----- have produced new cars.
California is starting to build hydrogen filling stations.
Range is comparable to gas-powered cars, about 300 miles.
Automakers have avoided building fuel cell cars mainly because of the lack of filling stations.
Electric Power
Two carbon-fiber tanks store 11 pounds of hydrogen fuel under very high pressure (10,000 psi).
In emergencies ( a crash), sensors trigger shutoff valves to keep hydrogen from escaping the tank.
