  1. By: Justin Hewitt and Ian Allen Hydrogen Fuel Cells

  2. Outline • What it is • How it works • History • Uses • Environmental Impact • Advantages • Disadvantages • Outputs • Facts • Closing • Sources • Questions

  3. What is a Hydrogen Fuel Cell? • Energy converting cell • Consists of an anode, cathode, and two electrodes • Provides energy in form of electricity and heat

  4. How it works • Water put through anode • Power source hooked up • Hydrogen separated from Oxygen in water • Can be used to power different things • Demonstration

  5. How It Started • Invented in early 1960’s • GE employees Thomas Grub and Leonard Niedrach • NASA • Continued to revise and edit cell

  6. Uses • Transportation • Cars • Honda FCX Clarity • BMW Hydrogen 7 • Buses • Planes • Telecommunications • Stationary Power • Homes • Businesses

  7. Environmental Impact • Hydrogen fuel releases water emissions • Reduces global warming effects • Reduces fossil fuel demand

  8. Advantages • Plentiful • Renewable • Contains a lot of energy

  9. Disadvantages • Hard to store • Requires energy to produce • Selective in locations • Requires careful handling

  10. Outputs • Type 1 • Hydrogen fuel separated from Oxygen • Type 2 • Creates waste energy in separation • Requires high-pressure storage • Type 3 • Can be separated using clean fuels • Powering vehicles with virtually no emissions • Type 4 • Not as available as planed

  11. Facts • By 2040, Hydrogen will reduce oil demand by 11 million barrels/day • Lightest of all fuels but produces 3 times as much energy/pound of gas

  12. Closing • Hydrogen is reliable and clean energy • Can be used in many ways • Need more to become available
