sebosfato,your one post you say that you can't extract electrons from the water with only the two leads hooked to the cell.If you go back and re-read the electron extracting circuit,and look at the schematics,you will see that the extraction only takes place when the pulses are in their off state.Then another circuit turns on and removes the electrons,again while the pulsing circuit is in it's off state.This circuit is tied into the positive wire going to the cell,and thats where the electrons are removed.
