So first off this is a hydrogen fuel cell. This car obtains hydrogen by electrolysis, which is the splitting of water into hydrogen and oxygen by the simple use of electricity. The hydrogen then is channeled into a small balloon like fuel tank which you can see in the pictures. Now the hydrogen is put into the actual fuel cell. This type of car is oxygen breathing so it simply takes oxygen from the atmosphere and combines it with hydrogen to create water and free electrons which are made to do work which turns the wheels. I thought it was a pretty cool little car and it can be powered by AA batteries or even better a solar panel which came with it. Well I just thought that I would tell you about this and possibly get you interested in fuel cells, though really just to show off some of my toys.
And here is a slideshow of all the pictures if you want to see them: http://www.flickr.com/photos/22640592@N08/show/
