Hydrogen: Fuel of the Future?

total heat: provide of the future?
Our day to day lives take on become dependent on the congenital combustion railway locomotive and at that placefore embrocate. We need it to get to work, to transport our food bewitching much every aspect of our lives has been shaped by a dependency on the internal combustion engine and oil. This is unreassuring when figures state that if the world carries on with its current rate of inlet and no new reserves are found that there is only approximately 40 years worth of oil left (The Telegraph, 2004)¹. It is clear then a solution is needed. victimization Hydrogen as the give the sack to indicant a Hydrogen fuel cell has long been touted as the solution to this problem. buns Turner of the US Department of cyphers National Renewable Energy Laboratory in Golden, Colorado, is a leading advocate of total heat. He argues (2004, p 972)² that using renewable energy to generate hydrogen is the only green way to produce the energy to pass along our cars and trucks. If a solution exists, why then are the internal combustion engines in our cars not being replaced with hydrogen fuel cells?

In order to understand the reasons behind the lack of keep in replacing our dependency on oil with hydrogen an understanding of how a fuel cell works is required.



fundamentally a fuel cell is an electro chemical cell that converts chemical energy from a fuel into electric energy (Appleby, Anthony J.,2002)³. Fuel cells have many variations; though, they all work in the same(p) overall way. They consist of three sections which are fitted together: the anode, the electrolyte, and the cathode. At the interfaces of the three separate sections two chemical reactions occur. The net terminus of the two reactions is that fuel is consumed, water or carbon dioxide is the by product, and an electric current is created, this current is then used to power the load (See diagram 1)( Larminie, J., May 2003)?.

In the application of cars or other automobiles the load is an electric motor. In the archetypical...If you want to get a full essay, order it on our website: Orderessay
