We know how to make hydrogen, thats easy, you just take glucose (sugar's most basic form) and run it through a mitochondria without a membrane, which I believe scientists are comming close to synthesising. That produces hydrogen and oxygen. The main problem with hydrogen fuel, and fuel cells is that hydrogen does not store very easily. You would need a gas tank at 10,000 lbs per square inch to store the same amount of gas as in a regular gas tank. That is a lot of pressure, and combined with the high potential that hydrogen has, it isn't very feasable. We need something to hold it together without anything else touching it.
ADDITION:
If you've heard of ATP (Adenosine Tri-Phosphate) I think that should be the next big fuel, because it has more energy than basically any molecule out there. ATP is whats produced by all living things to be able to move.
ADDITION:
As I said earlier, there were experiments that came close to cold fusion. I found an article that explained what actually happened in 1989 and now in 2002. They seemed to have actually created some interesting results.

OMFG... You cannot take organics, and convert them to mechanics you idiot...
Here's why hydrogen wont workWell, I don't really know how we could harness ATP, but that is what our mitochondria make. ATP basically makes any moving part on our body move. If we could somehow create that step in cars, we could have cars that run off sugar.

Again, you cannot take organics, and convert them to mechanics....
Hydrogen would work, but like it has been said before, there is not anything strong enough to hold the Hydrogen. And they don't even have an engine that is strong enough, or even capible of processing raw Hydrogen.
