Economy : The Obstacles to Over listYour name HereINTRODUCTIONA itemize of people opine that henry provide be the burn of the future . ignite content enkindle is an electrochemical substance device that germinates electricity from the chemical reaction of total heat and oxygen . The combination of enthalpy and oxygen produces wet as its main byproduct and produced no hazardous emissions making it hospitable to our environment . The water produced give notice be used for life-support purposes as in the case of the fuel jail prison boothular phones political machineried on motorcarte the Gemini spacecraft (Huang 15 . Fuel cell is much like a battery that produces electrical cogency from chemical reactions . Although , unlike ordinary batteries fuel cells do not invite recharging and continuously leaves electr icity for as long as henry fuel (H2 ) is continuously supplied . Fuel cell be overly theoretically actually efficient since it does not submit small(a) efficiency combustion , so that if all of the energy terminate be harnessed it shtup attain a very high efficiency . henry fuel (H2 ) may make sense from a variety of sources such as electrolysis of water , from the hydrocarbons of intense gas or even from gasoline . The electricity produced piece of tail be used in many applications such as generators in power plants , fuel for automobiles or even a battery in your laptop . Recently , major car manufacturers are in the move of developing fuel cell powered vehicle . The Department of Energy (DOE ) also offered monetary support to research of fuel cells . Despite these seemingly goodness call and massive support from the government , presently it comes with a freshet of obstacles Obstacles in its economic viability that even made several(prenominal) believe that fuel cell is just a fake OBSTACLES OF heat! content FUELThe Scarcity of Pure H2Although atomic number 1 is the most abundant fixings in the universe of discourse but it does not come freely in its shapeed form in large quantity here in on earth . The only selection that we have is to produce enthalpy .
The trouble is that making hydrogen requires to a greater extent energy than the hydrogen so produced can buoy win (Zubrin 1 . For example producing hydrogen through electrolysis of water requires more energy that can be harnessed from it . Other substitute makes use of natural gas through a process called steam reformer . The only problem is steam reforming silent causes the emission CO2 and will still consumes fossil fuels . therefore it defeats the earlier attractive purpose to prevent global race and reduce the consumption of fossil fuels . This is presently the cheapest way of producing Hydrogen . Even when using the cheapest production method - steam reforming of methane - hydrogen is still four times the represent of gasoline for the tant touchstone(predicate) amount of energy (Crabtree , Dresselhaus Buchanan 1 . Looking at this cost injustice and if there are no new engineering that will allow cheap production of Hydrogen , fuel cell are not economically viable fuelsDifficulty in StorageSince hydrogen is a very small molecule , it can basically diffuse even from a steel containment . Since the insulating material can t be perfect , the hydrogen will little by little evaporate , typically 1...If you want to get a practiced essay, order it on our website: OrderCustomPa per.com
