  1. Hydrogen Fuel Cells John Spellacy, Charlie Siford, Maggie frAgapAne, Kaylynn VIdmar

  2. History • The first Fuel Cell was conceived by Sir William Robert Grove in 1839. • The first bus powered by a Fuel Cell was completed in 1993. • Daimler Benz and Toyota launched photo type fuel-cell powered cars in 1997. • Fuel cells have been around for over 150 years.

  3. Fun facts • Hydrogen is a renewable, efficient, and clean source of energy. • Composed of a single proton and a single electron. • Hydrogen is estimated to be 90% of the visible universe. • Hydrogen is the raw fuel that most stars “burn” to produce energy. • Hydrogen is the most popular gas in the universe. • The sun’s supply of hydrogen is expected to last another 5 billion years.

  5. More fun facts • Hydrogen is the first element on the periodic table. • Hydrogen molecules consist of two hydrogen atoms. • Hydrogen storage is a concern. • Hydrogen is a colorless, flammable gas. • Hydrogen is not an energy, but it is a carrier. • Hydrogen fuel cells produce electricity by combining the elements hydrogen and oxygen. • Hydrogen is the most abundant element in the universe. • A hydrogen atom has only one proton and one electron.

  6. Where hydrogen fuels cells are found • Hydrogen is found in many organic compounds. • Hydrocarbons make up fuels such as: • Gasoline • Natural Gas • Methanol • Propane

  7. Equipment • Workers should use appropriate protective clothing. • Equipment must be carefully selected and maintained to be effective in preventing skin contact. • The selection of the appropriate personal protective equipment includes • Gloves • Sleeves • Encapsulating suits

  8. ADVANTAGES • Emits only water vapor, assuming there is no leakage of hydrogen gas. • It can store up to three times as much energy as natural gas. • fuel cells are energy conversion devices. • They convert stored energy within a fuel into usable energy. • Fuel cells offer the ability to generate heat and energy at the point of use. • Traditional electrical infrastructure means that large amounts of electricity are generated at central locations where the resulting heat is not usually used effectively. • Different types of fuel cells can work on a range of different fuels.

  9. Disadvantages • Fuel cells are expensive. • Electricity generated by fuel cells in cars costs thousands of dollars per kilowatt • They are energy losers because it costs more to produce hydrogen than is earned by using hydrogen in fuel cells. • Prototype fuel cells last only 1/5th as long as they would be needed to make fuel cells cost-effective. • There is no hydrogen infrastructure to supply coast-to-coast delivery of hydrogen fuel. • They are energy losers because it costs more to produce hydrogen than is earned by using hydrogen in fuel cells:  • Electricity generated by fuel cells in cars costs thousands of dollars per kilowatt:  This would have to fall by a factor of 10 for fuel cells to become economically viable.

  11. Fuel cells in our daily lives! • Fuel Cells are used in many things such as: • Cars • Homes • Airplanes • Appliances Honda Clarity 

  12. HYDROGEN FUEL DIAGRAM

  13. DEFINITIONS • Methanol- a toxic, colorless, volatile flammable liquid alcohol, originally made by distillation from wood and now chiefly by oxidizing methane. Also called methyl alcohol. • Propane- a flammable hydrocarbon gas of the alkane series, present in natural gas and used as bottled fuel. • Encapsulating Suit- a protective coating or membrane.

  14. QUESTIONS • What is the name of the suit you need to wear while handling hydrogen fuel cells? • What are fuel cells used to operate? • Are fuel cells expensive? • What is one advantage of hydrogen fuel cells? • What is one disadvantage of hydrogen fuel cells? • Where are hydrogen fuel cells found?
