Hydrogen Fuel Cells: Fueled By Natural Gas Fossil Fuel Emission Levels
Pounds per Billion Btu of Energy Input Pollutant Natural Gas Oil Coal
Carbon Dioxide 117,000 164,000 208,000
Carbon Monoxide 40 33 208

Fuel Cell
Electrolyte is a seperator.
Electrodes. Where the electro cehmical reactions occur.
Two bipolar plates the connect the current and build voltage from the cells.
Gallons in a barrel: 42 Gallons
Energy in a gallon of gas: 132x106 Joules
Energy used by petroleum cars per year: 30 Billion barrels

Gasoline Data Gasoline used in cars per day: 21Millions barrels
Natural Gas Energy produced from natural gas: 646,756,778,902,080 Gallons
House hold consumers: 604,556 McF
Energy Produced by all: 2,162,975 McF
Energy produced from natural gas: 2 KWH
Efficiency of hydrgen cars: 23KWH/100 km

Advantages
The car runs much longer and more efficient.
It produces little to no emmisions.
We have lots of natural gas to use.
The fuel cell runs on electricity so it can be easily
hooked up and charged in a designated fuel
dock.

Natual Gas Graph Disadvantages
Fuel cells are currently very expensive, but since they have a simple construction, mass production costs would become extremely low.
Prototype fuel cells last only 1/5th as long as would be needed to make fuel cells cost-effective.
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.
Comparison
547,500,000,000 billion gallons of gasoline used per year in the world.
1747.47 trillion gallons of natural gas is left on the world.
So for a while we could run on only natural gas in our cars but like every non renewable
it will run our eventually run out.
Uses now
Right now hydrogen fuel cells are still prototypes.
They are expensive and hard to make.
Natural Gas is used for cooking, heating, cooling, providing energy for power plants
As you can see Natural Gas is also being used more for electricity production.
