Can’t you just break down water, use the hydrogen to power the electric motor, and I don’t think O2 as a byproduct is bad, now this is of course an ideal condition, but why hasn’t this been looked into more?

    “Hydrogen powered” generally means burning hydrogen in oxygen to make water: 2(HH) + OO -> 2(HHO). To run a car on water as you say is a lot like trying to make a fire out of ash, rather than wood. You can’t burn the ash because it has already been burned.

      Technically speaking, no one outside of college demonstration engines are burning hydrogen. Almost all hydrogen powered EVs use fuel cell stacks that mediate the proton exchange through an electrolyte. This allows the capture of far more energy than could be possible by just letting the hydrogen burn, as in a internal combustion engine, for example.
