2 HistoryThe 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 factsHydrogen 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:GasolineNatural GasMethanolPropane
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 includesGlovesSleevesEncapsulating suits
8 ADVANTAGESEmits 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 kilowattThey 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.
13 DEFINITIONSMethanol- 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.
