Silver & Black asked:


We are doing a hydrogen-powered car for a sciende fair next week and we would like to know scientifically, why does the hydrogen car works. Like what does it react that makes the car work.

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

    H2(gas)+O2=energy

    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.

    If you need to know more about hydrogen economy, ask
