Electrolyte is fed by gravity from the bottom of a reservoir to the bottom hole of the cell and returns via the top hole to the top of the reservoir.
Check out my thread "Painless experiment in HHO" under General Discussion, I have youtube videos I've made detailing how to build a cell from Lowes parts. My channel on youtube is called 'PainlessHHO'.
Good luck! Dry cells rock!
