      fuel cells do not burn hydrogen.

      Why not? Isn’t burning a common term for exothermic oxidation? As in 2H2 + O2 -> 2H2O + heat

        Because that’s not what hydrogen fuel cells do. Yes, you could make a hydrogen ICE car, but that’s not a fuel cell car. Fuel cell cars use supplied hydrogen run through a grid to combine with atmospheric oxygen and make electricity and drive electric motors. I had the same misunderstanding for like a decade. Hydrogen is nowhere near energy-dense enough to be feasible as an ICE fuel
