If you "prevent" a coating of Al Oxide forming then no reaction has taken place!
In addition, have you any idea how much energy it takes to free aluminium from its mineral oxides, like bauxite? - A damn sight more than you'll ever get back by using it to strip oxygen atoms of water molecules! ... so, at best you have a rather inefficient battery here.
Conclusion: so far as drivers saving fuel (or resources, or the the planet), this belongs in the Unicorn cage!
