1. HYDROGEN FUEL CELL TECHNOLOGY

2. WHAT IS A FUEL CELL?
A Fuel Cell is an electrochemical device that combines hydrogen and oxygen to produce electricity, with water and heat as its by-product.

3. WHY IS FUEL CELL TECHNOLOGY IMPORTANT?
Since conversion of the fuel to energy takes place via an electrochemical process, not combustion It is a clean, quiet and highly efficient process- two to three times more efficient than fuel burning.

4. HOW DOES A FUEL CELL WORK?
It operates similarly to a battery, but it does not run down nor does it require recharging
As long as fuel is supplied, a Fuel Cell will produce both energy and heat

5. HOW DOES A FUEL CELL WORK?
A Fuel Cell consists of two catalyst coated electrodes surrounding an electrolyte One electrode is an anode and the other is a cathode

6. HOW DOES A FUEL CELL WORK?
The process begins when Hydrogen molecules enter the anode The catalyst coating separates hydrogen’s negatively charged electrons from the positively charged protons

7. HOW DOES A FUEL CELL WORK?
The electrolyte allows the protons to pass through to the cathode, but not the electrons
Instead the electrons are directed through an external circuit which creates electrical current

8. HOW DOES A FUEL CELL WORK?
While the electrons pass through the external circuit, oxygen molecules pass through the cathode
There the oxygen and the protons combine with the electrons after they have passed through the external circuit
When the oxygen and the protons combine with the electrons it produces water and heat

9. HOW DOES A FUEL CELL WORK?

10. IMPORTANCE OF HYDROGEN
Fuel Cells require highly purified hydrogen as a fuel
Researchers are developing a wide range of technologies to produce hydrogen economically from a variety of resources in environmentally friendly ways

11. IMPORTANCE OF HYDROGEN
Hydrogen is a secondary energy resource, meaning it must be made from another fuel
Hydrogen can be produced from a wide variety of energy resources including:  Fossil fuels, such as natural gas and coal  Nuclear energy. - Renewable resources, such as solar,water, wind and biomass

12. HYDROGEN PRODUCTION
The biggest challenge regarding hydrogen production is the cost Reducing the cost of hydrogen production so as to compete in the transportation sector with conventional fuels on a per-mile basis is a significant hurdle to Fuel Cell’s success in the commercial marketplace

13. HOW WILL THE HYDROGEN BE STORED?
Developing safe, reliable, compact and cost-effective hydrogen storage is one of the biggest challenges to widespread use of fuel cell technology Hydrogen has physical characteristics that make it difficult to store large quantities without taking up a great deal of space

14. HOW CAN FUEL CELL TECHNOLOGY BE USED?
Transportation Stationary Power Stations Telecommunications Micro Power

15. HOW CAN FUEL CELL TECHNOLOGY BE USED?
Transportation
 All major automakers are working to commercialize a fuel cell car
 Automakers and experts speculate that a fuel cell vehicle will be commercialized by 2010
 50 fuel cell buses are currently in use in North and South America, Europe, Asia and Australia
 Trains, planes, boats, scooters, forklifts and even bicycles are utilizing fuel cell technology as well

16. HOW CAN FUEL CELL TECHNOLOGY BE USED?
Stationary Power Stations
 Over 2,500 fuel cell systems have been installed all over the world in hospitals, nursing homes, hotels, office buildings, schools and utility power plants
 Most of these systems are either connected to the electric grid to provide supplemental power and backup assurance or as a grid-independent generator for locations that are inaccessible by power lines

17. HOW CAN FUEL CELL TECHNOLOGY BE USED?
Telecommunications
 Due to computers, the Internet and sophisticated communication networks there is a need for an incredibly reliable power source
 Fuel Cells have been proven to be 99.999% reliable

18. HOW CAN FUEL CELL TECHNOLOGY BE USED?
Micro Power
 Consumer electronics could gain drastically longer battery power with Fuel Cell technology
 Cell phones can be powered for 30 days without recharging
 Laptops can be powered for 20 hours without recharging

19. WHAT ARE THE BENEFITS OF FUEL CELL TECHNOLOGY?
Physical Security Reliability Efficiency
Environmental Benefits
Battery Replacement/Alternative Military Applications
