Fuel Cell or Battery Essay -- Environment, Carbon Pollution

IntroductionAn increase of carbon pollution around the instauration has called for better options for the future of motoring. The two types of motoring options which have been developed argon the hydrogen force out booth and electric battery vehicles. Both of which leave alone pros and cons within the system, on the environment and cost wise. Hydrogen displace cell vehiclesA hydrogen provoke cell is an electrochemical cell which right off converts the chemical energy in hydrogen and oxygen to electrical energy with dainty water (figure 1). In general fuel cells have a standardized arrangement which consists of an electrolyte and two electrodes, but there are many types of fuel cells which are classified by the kind of electrolyte used (DOE muscularity Efficiency, 2006). An electrolyte is a liquid or gel that contains ions and can be decomposed by electrolysis and is bequest in a battery. The hydrogen fuel cell pathway consists of three conversion stages, the conversion of electricity to hydrogen, the conversion of hydrogen back to electricity and finally, the conversion of electricity to mechanical energy (Stephen Eaves, James Eaves, N/D). A Polymer Electrolyte Membrane (PEM) fuel cell is widely regarded as the most lustrous for light-duty out-migration. Hydrogen gas flows through channels to the anode, where a throttle valve causes the hydrogen molecules to separate into protons and electrons therefore increasing the production of energy (DOE Energy Efficiency, 2006). The Polymer Electrolyte Membrane also operates at a temperature of 50100C and has a 5060% electric efficiency . (Bill Siuru, 2007) As the electricity production process is direct through an electrochemical device in a fuel cell, it never goes through the step of being a high-temperature gas through norm... ...drogen vehicles were to be more widely used, methods of producing hydrogen in a cost-effective way would have to be developed and producing plenty to power an everyday car w ould also be a challenge (U.S. Department of Energy 2010).Conclusion Fuel cells are clean, fuel efficient, and fuel flexible. Any hydrogen-rich material can serve as a strength fuel source for this developing technology. Although it is reduces carbon emissions new research lead have to be carried out to ensure it becomes cost-worthy for everyday users. Battery cater cars are for the moment the most viable and inexpensive option yet the carbon emissions are adding to the already thinning atmosphere. By implementing hydrogen fuel cells as an alternative for maybe large forms of transport there leave alone be a significant reduction of greenhouse gases for everyday transportation users.
