Environmental Science Phase 4 Individual Project Essay

Environmental Science Phase 4 Individual Project - Essay Example The disadvantages with the batteries of electric cars, however, include their range, long recharging process and huge dimensions. The short distance travel, normally about 100 miles maximum, makes it impossible for electric cars to be tested in long travels due to the minimum of 5 hours recharging (Lee, 2007). There are various kinds of fuel cells, but the one best applicable for automobiles is pertained to as the (PEM) fuel cell. Some of its primary aspects are its capacity to ignite the engine immediately and to function at the worst conditions, which is very beneficial due to the fact that it does not consume much energy in order to function. However, the efficiency of fuel-cell-powered vehicles is hindered by the level of fuel in its tank (Sterrett, 1994). Most fuel cells for cars are also complicated and weigh heavily: a tremendous disadvantage for automobiles. The most recommended alternative fuel for cars that does not cause pollution is the hydrogen fuel. Hydrogen fuel possesses tremendous potential as a fuel source for the next hybrid of automobiles. They do not possess limitations like what normal car batteries have. Hydrogen is burned by a chemical process that does not cause pollution. Hydrogen fuel basically integrates hydrogen and oxygen in the chemical process that equates into electric power and water as end products. Add the fact that hydrogen is the present in every surface of the Earth. Because of these excellent qualities, hydrogen has normally been pertained to as the best fuel source available on Earth. Its primary reserve in this planet is water which is also abundant everywhere (Poole, 1992). The utilization of hydrogen as a fuel source for cars perfectly coexists with the environment, and not harmful. It is very impossible for Earth not have supplies of hydrogen. Hydrogen fuel is the recommended
