All about electrolysers, HHO, joecells ect. :)

small electrolyser

Hallo!
today we have finished my friends electrolyser, it is made from 316 grade stainless, with plexiglass covering plates, and vinyl sleeves 4mm thick between plates. plates size are 166x255mm
there are 43 plates - it means there are 6 sections with 7 cells in each. when using it in car where is ~13,5V useable voltage, we can get around ~1,92V on each cell.

now the electrolyser are getting conditioned, it draws about 0,3A @12V.
i will change electrolyte after 2 days, and repeat this process 2 more times.
electrolyte is KOH with distyled water.

ok. so there are some pictures

summary quantity of used stainless steel there are 2 square meters.

also, there are, i think, some simple and good bubbler idea - you can use plastic pipes, but connections (connections for vinyl tubing) are made in plastic covers. they are completely flat, and you can screw a counter screw-nut on inside of the cover. so the connection will be very good and strong, not like gluing the connector to plastic cover with epoxy. (i used white teflon band (seen in photo) to avoid leakage betveen plastic cover and conector)

Smack HHO

This is where I am with my generator...

Hoping to rough it in this week!

nice work there:P am i completely off when i'm guessing you're from Norway? or perhaps Denmark?

He is from Latvia, like me

Aha it was just the "hallo" part that set me off.

Good job

Hi Lemontree,

Wonderful cell. So you have total of 6 section with 7 cells each section. After conditioning, try to connect just one section (7 cells) to your car alternator. See how much current draw.

To get good production, each cell needs about 2V. With series cell, use simple measuring formula. 10A for 1LPM of hydroxy. So if your cell draws around 5A, that means it producing 500mL hydroxy.

Keep up your good job.

Dont for get to SAND your plates in an X!
This will also ndetermined how much gas you get.

thanks for suggestions!

with this same koh concentration, at first i tested some cells just for curious testing. so i connected 3 cells between 12 volts, and they draw 49amps, than i connected 5 cells - and they draw ~10,90A, but when i put 7 cells - they draw no amps. but, when i connected all 6 sections togeather with 7 cells in each - i get these 0,3A, so i decided it is enough for conditioning, and let it for 2 days to condition. the bubbles were coming up, and it worked slowly, merely.

now i disconect it, and prepare for fresh new koh solution, and will set up another 2 days for conditioning.

there are two holes in top, for gass outcoming (12mm diameter), and one 2mm diameter hole in bottom, for koh leveling. also gass output holes are zigzag patterrned - so one plate have holes in left side, another in right side, and so on. i think, this will make longer path for foam, so, will see, how foam will behave in this setup.

my apologies for my poor english

PS - the plates are not wery carefully grinded with sand paper, one side is grinded, other side has its original pattern - the stainless steel was with decorative polish on one side, so my friend decided not to grind this side, so the electrolyser we made for his car, so i accepted him not to grind this side, if he liked so much this original polish

Hi Lemontree,

Your cell and my cell are same design/concept. 0.3A is very little current draw for conditioning. You need at least 3A. The cell will get conditioned but will take longer time. I think using same electrolyte strength, use only 6 cells per section. This will push the amps higher a bit and just nice amp for conditioning.

What is your target LPM? If lower than 500mL than you may use 7 cells but for 1LPM and above, you cell needs at least 10A. That is only reason why I use 6 cell design in my car. Maybe after you fix the unit into your car then you can decide; 6 cells or 7 cells based on amps draw.

I tested my 7 x 2 closed cell design today. It did very good. It tested
at 1.7 L minutes at 20 amps. My Hydrogen torch flame was 3 inches long. On boost, 35 amps, my torch flame went to about 5 inches. It does heat up some, but not like smacks open bath design. It went from 92 to 99 in 24 minutes. when running around 20 amps. It is made with 15 plates 2.75 x 10" 316 SS and it is in 4" PVC.

2.75" x 10" = 27.5 sqr inches.

Rule of thumb = 0.25A per sqr inches.

27.5 x 0.25 = 6.875A (max).

Try not to go over 7A for your cell to maintain the efficiency. If not too much heat and can damage your cell insulator. With 7A should get around 700mL for series cell design should be sufficient enough for car booster. Too much hydroxy tend to counter productive.

Here is a good resource for anyone experimenting with HHO: Water splitting by HF

Seems they use only 2 electrodes in a jar of water, but with 300ma, 4.8v and 923 HZ they produce large amounts of hydrogen..

Don't believe everything you read.....

This video has been around A LONG Time....And no one has been able to validate it. A couple of buddies and myself built an Exact Replica, as far as Visually possible. Played with All the Frequencies in that area and got almost nill results. Without them showing the wiring and zooming out to confirm the claims, it is just not even reasonable to believe !

Heck I wish it were true, we would all be!

Well it is a good thing we have experienced users like you around to keep us on track!!


Maybe you could comment on my thread http://www.energeticforum.com/renewa...fuel-cell.html ? I am anxious to know if it is possible and how effective it would be.
