Title: Hydrogen Fuel Cell Cars: The Best Solution?


1
Hydrogen Fuel Cell Cars The Best Solution?
  • Tim Cahill and Ryan Saran

2
  • A Hydrogen car uses hydrogen as its on-board fuel
    for motive power.
  • Hydrogen cars covert hydrogen energy to torque by
    two methods
  • Combustion
  • Electrochemical Conversion

3
Combustion
  • A series of exothermic reactions between fuel and
    an oxidant accompanied by heat and/or light.
  • Hydrogen is burned by the engine.
  • Very similar to the way that gasoline is used in
    traditional cars.

4
Electrochemical Conversion
  • Hydrogen reacts with oxygen to produce
    electricity and water.
  • More common among Hydrogen car prototypes.

6
Hydrogen
  • Never found alone on Earth.
  • Easily extracted when in a compound.
  • Does not create energy, it carries it.
  • Hydrogen produced from natural gas only has 50
    of the original energy.

Benefits
  • The benefits of switching to hydrogen vehicles
    clearly outweigh the disadvantages.
  • Some advantages are
  • Zero Emission Technology
  • Mileage
  • Foreign Oil

9
Zero Emission Technology
  • Conventional fossil-fuel burning vehicles produce
    all sorts of poisons such as
  • Carbon Dioxide
  • Carbon Monoxide
  • Nitrous Oxide
  • The only emission of a hydrogen fuel cell car
    is water.

10
Foreign Oil
  • Developing a economy of mass produced and
    effective hydrogen cars will reduce our
    dependency on foreign oil.
  • Gas is clearly out of control and making this
    transition seems like the only way to get around
    at a reasonable price.

Problems
  • Although many advancements in hydrogen technology
    has occurred, there still are many problems such
    as
  • Fuel Cell Cost
  • Freezing Conditions
  • Storage
  • Hydrogen Infrastructure
  • Competition

13
Fuel Cell Cost
  • Currently, fuel cells are costly and fragile
  • We need to find a way to make inexpensive and
    tough fuel cells
  • Many designs require rare substances like
    platinum as the catalyst.

14

15
Fuel Cell Cost cont.
  • The catalyst can be contaminated by impurities in
    the hydrogen supply
  • A nickel-tin catalyst is the most popular
    alternative for this problem.

16
Freezing Conditions
  • Fuel cells produce water and utilize moist air,
    especially during startup.
  • The current high for startup in freezing
    conditions is 50 power achieved in 30 seconds at
    -20 C.
  • Goal 75 in 25 seconds at -15 C .

17
Storage
  • Hydrogen is considered a bulky gas.
  • It is very difficult to store large amounts in
    the liquid state and even harder in the gas state.

19
Hydrogen Infrastructure
  • Must get rid of typical gasoline pump stations
    and make them hydrogen pumps.
  • Hydrogen pump stations have already begun to be
    produced in many places around the world.

21
Hydrogen infrastructure cont.
  • In California, private and public initiatives
    have been taken to build a Hydrogen Highway
  • This has already begun production and has a
    sufficient amount of pump stations to support the
    travel of the latest hydrogen car prototypes.

22
  • President Bush has already raised 2 billion in
    Hydrogen Highway research and production.

24
Competition
  • There is not clear way to see which types of
    green car will be primarily in the future.
  • However, there is a strong possibility that all
    can be nearly perfect to the point where they are
    mass produced and sold to the public

25
Competition cont.
  • There are two leading solutions to the
    conventional gasoline car excluding the hydrogen
    car.
  • These the ICE Hybrid vehicle and the Electric
    vehicle.

26
ICE/PHEV Hybrid Vehicle
  • ICE Internal Combustion Engine
  • PHEV Plug-in hybrid Electric Vehicle
  • Can be plugged into a electric grid and achieve
    higher gas mileage and lower emissions that other
    hybrids.

27
ICE/PHEV Hybrid Vehicle cont.
  • In a 2006 article in Scientific American, argues
    that these vehicles will be standard in the
    automobile industry, rather than Hydrogen Fuel
    Cell Cars.
  • Have huge disadvantages in their cost, weight,
    and size of battery.

28
ICE/PHEV Hybrid Vehicle cont.
29
Electric Cars
  • Commonly referred to as a EV, which means
    Electric Vehicle.
  • Typically more fuel efficient that fuel cell cars
    on a wheel-to-wheel basis.
  • This is the main reason that these cars are
    gaining popularity.

30
Electric Cars cont.
31
  • Hydrogen cars are without a doubt the future.
  • This is our problem to deal with and solve.
  • A hydrogen economy is just around the bend. Will
    we be ready?
