The second method is to cause a reaction between hydrogen and oxygen in a fuel cell, in the course of electrochemical means. This reaction will create electricity which helps to drive an electric traction motor that gives power to the wheels of the vehicle. And the most interesting fact is that the only by-product of this reaction is water. Most of the car manufacturers find these two technologies as the most apt ones. And more that working on the conventional combustion engine the car makers are finding it more profitable and meaningful to work on the fuel cell.
The working of a fuel cell is not a very complicated one. A pack of individual fuel cells work in agreement to unite hydrogen that is stored in the tank with oxygen in the air, which will produce electricity. And the electricity thus produced will power an electric motor which drives the vehicle. This is the working of a fuel cell in very simple words.
But to be more definite, hydrogen fuel is supplied into the anode of each fuel cell. Hydrogen atoms with the help of a catalyst are split into electrons and protons. The electrons are then conducted through a circuit to generate electricity, while the protons are channeled through a polymer electrolyte membrane. The oxygen in the air comes into contact with the electrons and protons and the by product, water, is formed.
The revolutionary FCX Clarity from
Honda is named the 2009 World Green Car. The FCX is powered by an electric motor making use of the fuel cell stack developed by Honda. California has the strictest emission norms in the world. And this no carbon dioxide emitting and only water and heat emitting Clarity has now has selected customers in California. Honda is expected to make the car available to more and more customers. And this will depend on the availability of fuel.
