Essay - Fuel Cells Powered by Hydrogen Why Do We Need This...

Fuel Cells Powered by Hydrogen

***** do we need this technology?

***** need fuel cells powered by hydrogen to prevent air pollution, to decrease our dependence on foreign oil and because of the growing scarcity of petrochemicals..

***** advantages ***** ***** technology

The ***** cell efficiently converts hydrogen into electrical energy, meaning that fuel-cell powered automobiles can travel more than twice as far as today's ***** using the same amount of fuel. Therefore, ***** emission of carbon dioxide, nitrogen oxides and sulfuric oxides is significantly lower. Also, the ***** cell does not have moving parts, making it quiet and reliable.

The d*****advantages ***** this technology

Fuel cells currently have a problem with delayed start-up and automobiles using fuel cell technology cost significantly more ***** similar gas-powered cars. Vehicles powered by ***** cells are also heavier and more difficult to manage than those running on gasoline..

Alternatives to this *****

The alternatives to this technology include cars powered by gasoline, diesel fuel, battery, hydrogen without fuel *****, ***** electricity. There have also been many hybrid models such as ***** gas-electric vehicles.

Highlights of differences between this ***** and current technology

Gasoline-powered cars cause substantially more air and noise pollution than do fuel cell cars. Hydrogen in ***** absence of fuel *****s has a detriment*****l impact on the weight and size of the fuel storage system, preventing reasonable performance ***** ***** efficiency. Unlike cars powered ***** battery or electricity, fuel cell cars do not require recharge or plug in and can, therefore, travel greater distances.

***** to be overcome before this technology becomes "mainstream"

With the release ***** its new ***** cell automobile, Honda commented that it sill needed to evaluate fuel ***** ***** in ***** real world and to monitor the development of a re*****ing infrastructure to support the ***** car.

***** also stated ***** significant cost, technology and infrastructure issues remain ***** be addressed before mass marketing.

An analysis ***** ***** pros and cons

We will continue to move towards technologies that reduce automobile pollution. At this point in time there is inadequate infrastructure to support fuel cell *****s. It will take a long time to provide this ***** and ***** get automobile owners to switch to newer automobiles. In the interim, there's a ch*****nce ***** technological advances may produce an even ***** attractive option to the fuel cell.
