which material do you use between the plates as a waterproof seal?
also how do i clean the plates after having cut holes in them? i suppose soap or other cleaners aren't good when using them for electrolysis later? :/

The most simple and cheapest gaskets that i use are made from flexible PVC.
I buy it by my local store that sells large sheets for:
Teich Pfütze Tümpel for fisches in your garden... ;)
Not sure what the right german word is.
In English it is called a pond. In my country they say: vijver
The thinkness i use now is 1mm. It is similair as the Anton guys do. But that is just coincident.
I used in the past 0.5mm, but with my current material is found out that 1mm is better.
 
Make your gaskets as small as possible to maximize the use of your plates.
Last tip:
All holes in your plates MUST be out of synch of eachother.
Thise prevents leakage of current and makes your cell 10% more efficient.
 
What most people dont know is that sanding your plates help.It makes a larger surface on micro level.
About cleaning: if you use NAOH or KOH then you can be sure that your plates will be cleaned!
Hahahahaha.
If you rinse the plates proper after sanding should be sufficient.
Try not to touch the plates after the sanding.rinsing with your fingers.
Thats all.

Thank you.


"Teich" is the correct word ;)

Another question: how did you connect the plates?
I have 13 plates here, that'll make 12 chambers. At ~1.5V / chamber i would put ~18 Volts on the outer plates and leave the other ones in between unconnected. Will that work?

You only connect 2 endplates. Rest are neutrals.
My two endplates have special "ears" on which i can mount a connector on.
I have used also weldwire welded on plates, which is working fine as well.
If you work with a gapspace of 1mm, and you use KOH or NAOH, then a voltage between 1.5V and 2.2V should be enough to get the best performance/efficiency.
We can meet on MSN or skype if you like. Then we can talk about as much as you want.

Thanks. I read today that if one is using KoH for electrolysis the plates should not be sanded. It was reasoned that the crystalline structure of the steel surface is changed with sanding and with use of KoH the plates would get rust relatively quick.
Were some of your cell-plates rusting?

Thats the first time i heard about that fact on sanding plates. To answer your question, i havent got rust. The main issues with SS and KOH/NAOH is that if you use lots of amps that the plates will be eaten disintegrate.
In my 102 platecell, my amps will not be higher then 11 amps. No rust either.

OMG.....
 
Leaking current all over the place....
 
I must make a redesign of my waterreservoir/bubler and seperate them totally.
 
With high voltages like 200V, electrons leak thru the watertube, reservoir/bubler and gasoutlet tube, in stead of thru the plates.........
 
arggggggg

why don't you insert a valve for the reservoir supply line and close it when using the cell? Ocassionally you have to open it to let new water flow in, but the closed valve will not let current through the whole bubbler.

Thanks for thinking along, Haithar   :)
I just solved it with a new construction and materials..Later i show it all by picture of video.
