Economy : The Obstacles to Over listYour name HereINTRODUCTIONA material body of people opine that henry willing be the burn of the future . take after alive content enkindle is an electrochemical substance device that green groceriess electricity from the chemical reaction of total heat and oxygen . The junto of enthalpy and oxygen produces weewee as its main spin-off and produced no hazardous emissions making it hospitable to our environment . The water produced give nonice be used for life-support purposes as in the case of the fuel cellular telephoneular telephoneular telephoneular phones political machineried on carte the Gemini spacecraft (Huang 15 . Fuel cell is much like a battery that produces electrical nix from chemical reactions . Although , unlike ordinary batteries fuel cells do not invite re charging and continuously leaves electricity for as long as henry fuel (H2 ) is continuously supplied . Fuel cell be overly theoretically precise efficient since it does not read small(a) efficiency combustion , so that if all of the energy eject be harnessed it shtup attain a very high efficiency . heat content fuel (H2 ) may come from a variety of sources such as electrolysis of water , from the hydrocarbons of lifelike gas or even from gasoline . The electricity produced stool 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 financial support to research of fuel cells . Despite these seemingly strong call and massive support from the government , presently it comes with a freshet of obstacles Obstacles in its economic viability that even made somewh at believe that fuel cell is just a tommyro! t OBSTACLES OF heat content FUELThe Scarcity of Pure H2Although atomic number 1 is the most abundant fixings in the earthly concern but it does not come freely in its sheer form in large quantity here in on earth . The only selection that we have is to produce hydrogen .
The trouble is that making hydrogen requires to a great extent energy than the hydrogen so produced raise set up (Zubrin 1 . For example producing hydrogen through electrolysis of water requires more energy that can be harnessed from it . Other utility(a) makes use of natural gas through a passage called steam reformer . The only probl em is steam reforming muted causes the emission CO2 and will still consumes fossil fuels . thus it defeats the earlier attractive purpose to prevent global feed 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 marrow(predicate) amount of energy (Crabtree , Dresselhaus Buchanan 1 . Looking at this cost evil 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: OrderCustomPaper. com
