Essay on Fuel Cell Vehicles

Introduction
A fuel cell vehicle simply is an electric vehicle that makes use of hydrogen as fuel for the production of electricity instead of making use of the battery. Instead of using moving components for chemical processes, the fuel cells make use of a certain catalyst that then utilizes the oxygen from the air and combine it with the hydrogen that is used as a fuel to generate the electric power. When hydrogen is used as fuel, the gas is stored, taking safety precautions, in the vehicle within the pressurized tank that has the utility of storing hydrogen gas pressurized three times more than usual.

Then the hydrogen gas is supplied at a very less pressure to the fuel cells as compared to the high pressure at which other fuels like gasoline is supplied or injected in to the combustion engine producing electric power. However, the concept is still in its prototype stage, the fuel cell vehicles provide greater than before efficient and effective means of transportation as compared to the gasoline vehicles in addition to providing the zero emission vehicles. Previously, the fuel cells were used in spacecrafts that made use of liquid hydrogen as fuel that produces electric current. The technological basis is same as that used in space technology. When the catalyst covering an electrode comes in contact with the hydrogen fuel, the hydrogen atom is broken in to protons and electrons. When the electrons move, they generate electric power that is then transmitted to the controlling inverter unit.

This then converts the received electricity to be used by the motor converting the electric energy in to mechanical one thereby steering the wheels. What results from these chemical, electrical and mechanical processes as a by-product are some heat energy and water...............
