Distance between postive and negative in cells

[bubblemonkey2]

Im wondering is there a difference in production in HHO generators when the Postiive plates/wires are further apart from the negative plates/wires vs closer together?

I notice a lot of cells use tubes which are VERY close in proximity.. yet when I saw Aarons Wire "fin" design he was getting good production with a wire fin placed several inches away from the two postive plates? 

Just curious about this any feedback welcome!

During the simple electrolysis ions are moving the charge from the electrodes around.The closer the electrodes the faster ions can travel between them (shorter way) the more amps you can feed in your cell.But i feel it would be a problem with too close electrodes(less than 1-2 mm distance).On every electrode you get gas bubbles , if the space is small enough almost all of the space between the electrodes will have contact only with gaseous bubbles and not with water.Bubbles like to stick between small objects(water surface tension? ).It means no ions there and no current.So your electrodes will have small effective area of contact with water and cell would produce less.
At my cell i used two SS sponges(the one u scrub your dirty dishes/grill when washing them) and high amount of KOH as electrolite.Electrodes have a big surface area,yet the amp are very low around 4-5 A with 12 V.I expected 30A or more.I guess the problem is with the sponge that is is "holding" a big amount of produced gas inside and that is reducing the effective surface area.I guess the high surface tension of water is to be blamed,maybe adding of some additives can help.As for now i am building another cell with SS balls as electrodes we will see what will be the difference.

Most people designing cells like to keep their electrodes between 1/8" (1.6MM) - 1/4" (6.35MM) apart to allow for the flow of bubbles off of the surface of the electrodes and electrolyte to replace the bubbles and allow for easy flow of voltage and current across the plates of the electrodes. I would recommend you watch ZeroFossilFuel's videos http://www.youtube.com/zerofossilfuel or Sidyoung's videos http://www.youtube.com/sidyoung on Youtube, if you want more info, especially their earlier videos. Another good bunch of videos to watch are by John Aaron http://www.youtube.com/johnaarons.There are a multitude of videos that have some kind of reference to the distance between the plates posted on youtube, all you do is have to search for them.

you typically will draw more current when your closer together too... but i like being close in my cells....

True, True, it does draw more current (amperage) when the plates are close together. If the cells were farther apart it would also draw a large current to push the ions across the electrolyte, because the current would have to travel farther to get to the negative from the positive plate. It would possibly cause a lot more heating of the cell by a larger current flow heating the electrolyte. The most difficult part of building a hydrogen generator is trying to find that sweet spot, the right distance between the plates and drawing the least amount of current and causing the least amount of heating of the electrolyte in the cell.
