The electricity generated by the fuel cell could be used to drive a vehicle. The heat from the fuel cell could be used to separate the pure water from the fuel cell into hydrogen and oxygen. And if all that worked you would have a perpetual motion machine.
Instead of fighting the laws of physics, generate the hydrogen offsite, ideally with clean(ish) energy, then transport it to filling stations just as gasoline is produced offsite and transported to gas stations. A car equipped with a fuel cell would then be an EV with a hydrogen fuel cell rather than a lithium battery.
Hydrogen safety in transport and storage is a big problem but maybe solvable.

Agreed, putting a box on every car would be foolish. Bad enough storing what destroyed the Hindenburg...
