Hydrogen Fuel Cell cars have been in the planning for a few years now, but we have still yet to see any mass production of this clean fuel source for cars. Toyota is close, but we will have to wait until 2015. So what is so great about this fuel source and how does it work?
This is one of the most common questions asked, and although it is a step in the right direction and a shift away from our fossil fuel dependency — the technology used is not without its problems. However, there are advancements in the technology all the time, the main issues is with the price of R&D and manufacture costs.
Karim Nice and Jonathan Strickland from How Stuff Works have written an extensive article on this technology in the hope of helping us understand how Hydrogen Fuel cells work. They also look at other alternative fuel sources and how they compare to the current choices.
The fuel cell is a very complex device that converts hydrogen and oxygen into water, which in turn produces electricity. The idea sounds simple enough, but as we mentioned above is not without its problems, one of them being how costly platinum is, something that is used to develop the cell.
