Hydrogen Fuel Cell

  1. 1. Different Ways To Generate Electricity Hydrogen Fuel Cell
  2. 2. Electricity is the flow of electrical power or charge. It is both a basic part of nature and one of our most widely used forms of energy. Its not a source of energy but an Energy Carrier. What is Electricity?
  3. 3. The energy sources we use to make electricity can be renewable or non-renewable, but electricity itself is neither renewable nor non-renewable.
  4. 4. Electricity travels at the speed of light . That totals more than 186,000 miles every second.
  5. 5. Present sources of energy
  6. 6. Harnessing The Power Of Hydrogen
  7. 7. Hydrogen ?? What is it ? Hydrogen gas glows purple when ionized. I am the lightest element and am gas at normal temperature and pressure. I condenses to liquid at temperatures of - 253° Celsius.
  8. 8. Hydrogen ?? What is It ? In Greek, hydrogen means "water- former". NGC 604, a giant region of ionized hydrogen in the Triangulum Galaxy Hydrogen is not a fuel…it is a way of storing and transporting energy , similar to a battery.
  9. 9. 93% 0.3% 0.7% 2.7% 0.2% 1.5%
  10. 10. But, Why Hydrogen ??
  11. 11. 2) CO + H2O → CO2 + H2 Steam reforming 1) CH4 + H2O → CO + 3 H2 Production of H2 Coal Gasification 18% of world production. Byproduct of steel industry. Primarily found in Europe and Asia
  12. 12. The hydrogen contained in a liter of water can be used to produce of electricity!
  13. 13. Thermo chemical Split water with chemicals and heat Photo electrochemical Split water using sunlight directly, or using chemicals and heat Biological Split water using organisms
  14. 14. How to use H2 as fuel ? Sir William Grove invented the first fuel cell in 1839.

  24. 24. From Laboratory To Road
  25. 25. Hydrogen Safety Hydrogen gas leaking into external air may spontaneously ignite. Moreover, hydrogen fire, while being extremely hot, is almost invisible, and thus can lead to accidental burns. reacts easily with air The most challenging properties of hydrogen are its high dispersability, its wide explosion limits, low ignition energy and its colourless flame. the hydrogen sensor detects H2 it shuts off the fuel cell via relay
