165% Faraday Current Efficient

[hkyle]

Hey Guys,
Just an update on my new cell...I will get some pics on my projects page as soon as possible (when I fugure out how). The new series cell has 45 cells runs on 123 volts 6 amps and makes 5 - to 6 liters / min of hydroxy. This test run was on cold electrolyte not sure how much more it will produce when warmed up. The cell remained cool.
100% would be 3 liters / min of hydroxy.

cheers.....

KEWL....dont forget to give good descriptions on such high out put...so's ya dont get hounded over it heh heh.Been a long time since everyone got some updates on board.Cant wait to see em.

Projects page is now updated. Take a look, give advice.

I am trying to build my own full size cell. What are the specs of your cell. Plate distances, electrolyte density....I'm trying to find as much info as possible so I have a decent cell to start experimenting with. Where is a cheap source of 316 SS. I do not have a machine shop, just basic tools and am looking for a place that will cut my plates to spec. I had a machine shop at work but they fired everyone and moved it to Mexico!! Damn Nafta!!

(What are the specs of your cell. Plate distances, electrolyte density)
The gaskets between the plates are made from 3/16 freezer curtain (the drapes that you walk through in a store freezer) I bought a 20 ft role for 30 bucks. I will post a picture of the gaskets.

For the electrolyte density there is only 1 table spoon of Lye / Liter of water. I am using reverse osmosis water from my tap. I found that this amount of lye works great for my cell.

(Where is a cheap source of 316 SS)
I purchased the ss plates from my local welding shop. The price of steel was 6$ per sq foot. That is why I went to 4X6" plates you can get more for you buck....6 plates / sq foot of ss.

I am able to go to the high school in my town and use the plasma cutter to cut my plates. There is no shear around here. ha ha

The front plate of my cell is just an old cutting board, I used to have a lexan front plate but it kept on cracking. So far the back plate has not broke, probable will soon though.

The cell is then bolted together with threaded rod.

So far I think I have spent about $150.00 on this cell.

Do you have insulation between each cell (hydrogen/oxygen separation)? Is it series/parallel? I don't mind spending a few bucks on my cell, I just want to spend a few bucks and have a working example!! I live on Long Island, I will have to find a local shop that will cut them straight. If I do it I will probably bend them.

[hkyle]

No the hydrogen and oxygen are not seperated. I still need to figure that one out.
This is a series cell design.
I just updated my projects page that shows the gasket and the ss plates.

[TheSpecialist]

So each of your plates +/- are isolated. Plate, electrolyzer, plate, insulator, plate, electrolyzer, plate....

I am only using the series cell design to get more familiar with making hydrogen. This is an extremely efficient way to produce hydrogen but there are also allot of down sides when making this. Chris has explained the down side on a few of his posts and I totally agree with him. For example if you are going to use a series cell like the one I have made it will not work well in a vehicle. There is the ability of the electrolyte to travel up the hydroxy line into the carb or injection rails if the cell does not remain level. Once this happens you get allot of liquid traveling up the tube. Another problem is filling the series cell and keeping that level constant, you can't see the electrolyte level between the cells so you never really know what the level is.

I need to figure out next how to separate the Hydrogen and the Oxygen from a series cell design. After that I would really like to get into the PWM side of things. I purchased a function generator for $30.00 a while back it is a 100Khz function generator, do a Google on CK307 and you will find it. I have absolutely no idea how to use this or any other frequency mod to drive the unit.

[hkyle]

Yes each plate is totally isolated from the other, this way you can garantee that you won't have any current leaks aruond the ss plates. You also want to make sure that the electrolyte level is always below the top the the ss plates aswell. For example if you have 12 plates in your cell when you apply 12 volts each cell should drop by 1 volt leaving 1 volt per cell of course this is just an example. You want to stay aroung 1.24 to 2 volts per cell any less you wont make any hydrogen any more you will make to much water vapour.

each space is the gasket.

I am an Engineer. The frequency side is easy. I have all that equipment at work. I'm in the process of designing a 12VDC 10-15Amp supply. I'm also working on a pulse modulator. If you have a function generator you can use it to switch a high power transistor or mosfet. This could supply high current to your system.
I have also been trying to determine the best method of keeping water out of the Hydroxy line. When I went to my local auto parts store they had a display of a car cover that allowed oxygen to pass through, but kept the water out. The display had a button you pressed which forced the air through the cover. The water was on the opposite side of the cover and did not seep through. Could that material be used to prevent the water from entering the Hydroxy line?

[hkyle]

yah I am still lost on the electronics part ha ha. Do you know the name of that material? Might just work.
Do you have any examples on how I could hook up this frequency generator? I need to see how it is done in order to figure it out.

Good going Hkyle

At 123 VDC and a 6 amp draw you've got yourself a 738 watt electrolyzer (123 x 6 = 738 watt) Now place that onto a 12VDC battery source system and you'd be using a whopping 61.5 amps (738/12 = 61.5)
Well, at least old Faraday's efficiency numbers aren't looking all that efficient any more are they?

[TheSpecialist]

The frequency generator is a low power device. You can connect it to a transistor or mosfet to have it switch high current. I'll see if I can post a schematic.
