Title: Racing With Hydrogen


1
Racing With Hydrogen
  • Fuel Cell Cars

2
Hydrogen is 1 on the Periodic Table
?
3
ENERGY!
4
Hydrogen is the most abundant element in the
universe.
5
Hydrogen does not exist in nature by itself, but
it is found as part of a compound in abundant and
diverse resources such as the fossil fuels
natural gas and coal.
  • What is the most abundant compound on earth?

The Hydrogen Car
Is it GREEN ?

The Hydrogen Car A Review
  • What exhaust comes out?
  • How does it compare to our cars?

Water H2O
It is cleaner !!!
20
The Hydrogen Car
  • Lets try out a model of the fuel cell car that
    burns hydrogen.
  • It has been charging up by separating water into
    hydrogen and oxygen.
  • Do you think it will move for us today?

21
The Hydrogen Car Data
  • How long did the car run on one fill up?

22
What have we learned ?
  • Is the hydrogen car an alternative to our
    gasoline or diesel cars and trucks?

23
A Look at the Data
From www.fuelcells.org
24
  • When the electricity needed for electrolysis is
    generated using wind or solar power, for example,
    electrolysis can be a clean and renewable way to
    produce hydrogen.

Electrolysis
wind farm
solar panels
25
Challenge Cost
26
Hydrogen can be produced at small stationsor at
large plants and delivered to users.
27
Hydrogen Storage
Hydrogen can be stored as a gas, liquid, and
even in a chemical compound.
28
The Hydrogen Storage Challenge
  • To store enough hydrogen on-board a vehicle to
    enable drivers to travel 300-350 miles before
    refueling

29
Hydrogen storage tanks
30
Hydrogen Delivery
Hydrogen pipelines exist only in certain regions
of the country.
31
Once hydrogen has been easily produced and
safely stored, it can generate electricity
using a fuel cell.
32
Hydrogen-powered fuel cells can supply energy to
power anything from automobiles to homes to
computers.
Picture it
33
Hydrogen is a clean form of energy. It can be
used in fuel cells to create electricity with the
only byproducts being water and heat.
34
What do you think?
  • Most cars burn gasoline.
  • What comes out of the car exhaust pipes?

Carbon dioxide carbon monoxide unburned
carbon water
35
What do you think?
  • What other fuels could be used?
  • 1.
  • 2.
  • 3.
  • Are they cleaner?

Solar energy
electricity
propane
YES
36
One Answer -- Fuel Cells
  • They use hydrogen as a fuel
  • Their fuel cell passes the gas through a proton
    exchange membrane or PEM
