  1. Hydrogen cars run on hydrogen fuel cells. So you have hydrogen. its kind of electropositive, at least relative to O. What the fuel cell basically does is have the H travel to bond to the O, but it splits H into H+ and e-. The e- take a separate route, and a stream of electrons is what is electricity. and then you get H20. So the car runs on electricity which it makes.

Here’s a link to a similar hydrogen car, like the one we are doing:
