A 1.5v drycell battery can separate oxygen from hydrogen, however if you wanted to use the hydrogen to turn a generator to charge the battery, the entire system would drain down to zero energy in a short time because it takes more energy to separate the hydrogen than is ever recovered.
If you start the system with a large battery and use the energy from the battery to split the H2O, you could get enough H2 gas to run the engine for a while, but eventually it will run out of energy from the battery. The system is a net sum loss system.

That will be interesting. Try collecting the Oxygen and using that first, in case the H2 blows up the engine.
