Benefits

NASA has used liquid hydrogen since the 1970s to propel the space shuttle and other rockets into orbit. Hydrogen fuel cells power the shuttle's electrical systems, producing a clean byproduct - pure water, which the crew drinks. A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water.

Fuel cells have a higher efficiency than diesel or gas engines. Most fuel cells operate silently, compared to internal combustion engines. Fuel cells can eliminate pollution caused by burning fossil fuels; for hydrogen fuelled fuel cells, the only by-product at point of use is water. www.fuelcelltoday.com/about-fuel-cells/benefits

What, Where, and How it's used!

Some tasks that hydrogen fuel cells can perform is making certian fuels like the fuel that NASA usews. It can also make fuel for cares like toyota.

Hydeogen Fuel Cells is also used in air planes.

Limitations

About Hydrogen Fuel Cells!

Hydrogen exists in almost all plant matter and also occurs naturally in water. Though the sun has a greater percentage of hydrogen gas, the gas is too light that it virtually disappears from the surface of the earth when conveyed by the sun rays. So, to effectively obtain hydrogen gas, it must be harnessed from water, natural gas or biomass.

COST

COST

This means that if natural gas costs $6/million BTU, then hydrogen will be $18/million BTU. Also, producing hydrogen from electrolysis with electricity at 5 cents/kWh will cost $28/million BTU — about 1.5 times the cost of hydrogen from natural gas.

EFFECTIVENESS

Effectiveness

Hydrogen fuel cell vehicles, which use electric motors, are much more energy efficient and use 40-60 percent of the fuel's energy — corresponding to more than a 50% reduction in fuel consumption, compared to a conventional vehicle with a gasoline internal combustion engine.

ALTERNATE SOURCE

Form replaced

Hydrogen fuel cells can be placed as an alternate fuel source for heat. it can produce the same amount of energy, just as much as heat can produce.

Transformations/Involve

More Info about Hydrogen Fuel Cells & Group Opinions!

A hydrogen fuel cell converts chemical energy stored by hydrogen fuel into electricity.Hydrogen-oxygen fuel cell. Fuel cells use the reaction between a fuel and oxygen to produce electrical energy. They are efficient and convert a large proportion of the chemical energy in the fuel into electrical energy.

Group Opinions!

Andrew: My opinion is that hydrogen fuel cells provide electricity wich we use to see and provide heat for us.

GROUP OPINIONS

Trent: My opinion on Hydrogen Fuel Cells is that they're helpful in getting rid of pollution when fossil fuels are burning. Also, the only by-product of Hydrogen Fuel Cells is water!

Chris: My opinion on hydrogen fuel cells is that is very important in everyday life. It is also amazing how they put hydrogen fuel cells on airplanes
