Fuel Cells and Hydrogen Cars

• By 8th Grade Student

2
How will hydrogen power replace fossil fuels?

• Hydrogen will slowly take over from fossil fuels
  as the main source of power. It will do this
  because hydrogen is easier to obtain and it wont
  pollute like fossil fuels.

3
How will hydrogen replace fossil fuels(cont.)

• It will also take over because it is cheaper to
  purchase and make. This will help it a lot in the
  long run to replace fossil fuels.

4
How will hydrogen replace fossil fuels(cont.)

• Hydrogen will also take over because fossil fuels
  will soon run out leaving us no choice but to
  switch. This is a huge reason for it to replace
  fossil fuels.

5
How will reducing our oil imports change our
relationship with the counties in the Middle East?

• If we reduce our oil imports with other countries
  of the middle east then it will be good and bad
  for us. It will be good because we will save
  money but bad because it will give us a bad
  relationship with them. If that happens, then
  there is no telling what they might do.

6
How will reducing our oil imports change our
relationships with the countries of the Middle
East?(Cont.)

• Anther way that reducing our oil imports will
  effect our relationship is that they may take
  away any other important items that we buy from
  them because of this. Some of these might be,
  well, fossil fuels. This is because if hydrogen
  cars fail then they may not sell us anymore to
  get back at us.

7
Where will we get and how will we make hydrogen?

• We will get our hydrogen from the air seeing as
  how it is the most abundant element in the
  universe.

8
Where will we get and how will we make
hydrogen?(cont.)

• We will also get hydrogen from water because
  hydrogen is the main component of water .

9
Where will we get and how will we make
hydrogen?(cont.)

• We will make hydrogen by using the Hydro-Gen. The
  Hydro-Gen separates hydrogen gas from the natural
  hydrogen-oxygen mix in standard tap water which
  will result in us making hydrogen.

10
Where will we get and how will we make
hydrogen?(cont.)

• Another way for us to make hydrogen is by sending
  electric waves through a liquid electrolyte
  comprised of water and Lye which causes the
  hydrogen molecules to separate from the oxygen
  molecules in the water. Also, this will give us
  hydrogen.

11
What are the disadvantages of petroleum fuels
used in cars?

• There are many disadvantages to using petroleum.
  One is that by using petroleum, you are polluting
  the air and the earth. Most of this pollution
  comes from large paper mills and factories, but
  it also comes from cars and other machines that
  use it for energy.

12
Disadvantages of petroleum(cont.)

• Another disadvantage of petroleum is that there
  is not enough of it left. We will probably run
  out within the next 30-40 years. This means that
  we will either have to ride bikes and horses or
  switch to hydrogen power.

13
Disadvantages of petroleum(cont.)

• Also by using petroleum, we are discharging the
  soil and water and causing acid rain to fall.
  This also brings about the chances of horrible
  climate changes.

14
How are fuel cells using hydrogen?

• One way that fuel cells can use hydrogen is by
  taking the hydrogen and combining with oxygen to
  form water without combustion. This way it forms
  electricity or in other words, energy to run the
  car.

15
How are fuel cells using hydrogen? (cont.)

• Another way for a fuel cell to use hydrogen is
  that it they take the hydrogen and store it in a
  metal so it can hold more than in anything else.
  This way you can travel farther on a tank of
  hydrogen. These are just a few ways that fuel
  cells use hydrogen.

16
Can a fuel cell take in water and put out
hydrogen and oxygen?

• In order for a car to take in water and put out
  hydrogen and oxygen, electricity must pass though
  the water molecule and split it apart into
  hydrogen and oxygen. It then uses the hydrogen in
  the water to make energy.

17
Can a fuel cell take in hydrogen and oxygen and
put out water?

• The net reaction fuel cell can take in hydrogen
  and oxygen and releases water. The equation used
  to do this is . It is able to
  do this by giving the hydrogen a positive and the
  oxygen a negative charge so the two will attract
  and form water.

18
What would a hydrogen economy look like?

• In a hydrogen economy, vehicles like cars and
  airplanes would use hydrogen fuel cells for
  power, rather than petroleum.

19
What would a hydrogen economy look like?(cont.)

• A hydrogen economy would look cleaner and be
  healthier for all people, plants, and animals.

20
What would a hydrogen economy look like?(cont.)

• If we had a hydrogen economy you wouldnt see any
  smog tests for tractors and other things like
  that.

21
What would a hydrogen economy look like?(cont.)

• You also wouldnt see as many problems with oil
  and other countries in the news anymore.

22
Where are hydrogen cars being used today and what
are other alternative fuels?

• An alternative fuel would be coal. This is
  because coal is a very abundant resource.
