You can't simply fling the atoms together, though. Hydrogen must be broken down into its positively and negatively charged particles first. A hydrogen fuel cell does just that. Much like in a battery, on one side of the fuel cell is the positive post, where the hydrogen is introduced. A polymer film allows only the atoms' protons to pass, stripping them from the hydrogen and leaving only the negatively-charged electrons behind.
The electrons are attracted to the positive side of the fuel cell, a phenomenon known as electron flow. But they can't pass back through the polymer film the way the protons did. Instead, they are directed outside the fuel cell through a circuit. When you add an electrical device like a car motor to this circuit, the flow of electrons powers it. As they continue along the circuit to the positive side of the cell, they pick up their protons, forming hydrogen once again. The hydrogen also bonds to oxygen from the surrounding air: The result is water.
The only byproducts of the electricity generated by hydrogen fuel cells are heat and water, which makes them an extremely desirable source of power, environmentally speaking. But hydrogen fuel cell kits currently exist only as limited-release concept cars or in miniature for RC cars or in hands-on science experiments for kids. A couple of big roadblocks stand in the way of wide deployment of fuel cells in the world's transportation fleets, namely cost and net energy yield.
Complete hydrogen conversion kits will soon be available for various late-model cars & trucks as well as individual system components for those who choose to assemble their own kits. Included in the kits (and also available separately) is our solar powered Hydrogen Generator that manufactures the Hydrogen fuel for your vehicle at virtually zero cost. Simply put, you never have to buy Gasoline again.
