    1. Hydrogen By: John Vang& Gee Yang

    2. What is Hydrogen is the simplest atom and is even lighter then air. A highly combustible gas and also very flammable. Made of a single proton an a single electron.

    3. How does Hydrogen work? Because hydrogen doesn't exist on Earth as a gas, it must be separated from other elements. Hydrogen atoms can be separated from water, biomass, or natural gas molecules. A fuel cell converts the chemicals hydrogen and oxygen into water and in the process it produces electricity acting like a battery, but fuel cells has constant flow so it does not dead out.

    4. Advantages • When hydrogen is burned, the only emission it makes is water vapor, so this advantage of hydrogen is that when burned, carbon dioxide is not produced causing Hydrogen to be less harmful. Hydrogen has the potential to run a fuel-cell engine with greater efficiency over an internal combustion engine. The same amount of hydrogen will take a fuel-cell car at least twice as far as a car running on gasoline

    5. Disadvantage • Currently, hydrogen is produced using coal, nuclear power, oil, or natural gas. These methods produce same amount of pollution as just burning gasoline. • But producing hydrogen fuel cells a more saver way but is extremely expensive, Electricity generated by fuel cells in cars costs thousands of dollars per kilowatt. Although this method doesn't generate any pollution, it is rarely used because it will cost too much money to be used widely.
