Introduction: The Basics of a Hydrogen Dry-Cell

Picture of The Basics of a Hydrogen Dry-Cell

This Power-Point Shows The Basics Of A Hydrogen Dry Cell.
Also Here: hydrogen dry cell PP
Some of the benefits of a dry cell are that it is much less corrosive than submersion.  They are also very efficient, some 90% and up, unlike the average 20% of a combustion engine.  They have much higher output than other generators too, small ones get up to 6 liters per minute, 3 huge party pop bottles in a minute.
The down sides are that they are extremely expensive, and ... I don't know what else but feel free to tell me.

Great collection of broken links.. very not usefull

what i ean is how do you get the electricity out of the cell? (author)TimmyMiller2011-11-10

Oh, lol, this is the other half. This is the HHO generator, you need to look up a hydrogen fuel cell. It uses the hydrogen that this produces.
this is how I first figured it out.

can i request the pdf of your hydrogen dry cell please? thanks for sharing your bright and great idea. my email add:

thanks a lot bro. (author)rainbowrider422011-11-11

Yea, I will put a pdf together, and I have an idea of my own that involves juice concentrate metal lids that I will be including and later putting into an instructible

ShamsR1 (author)jj.inc2015-01-16

Hi There,

I need the PDF ? (author)2011-11-08

Did you wan't a copy of the file, If so I can send you one, I will also throw in my latest Idea which is awesome and a ton cheaper. Please Include an email if you wan't the file and the link isn't working

TimmyMiller (author)jj.inc2011-11-09 is my email

p.s. how does this work?

Jaffasoft (author)2011-03-18

OK, the solution here as you rightly corrected below is that if you have the negative closer, i did pos-n-n-neg and it begins bubbling quiet vigorously.

The closer the you connect the neg the hotter and more nigerous it bubbles but things start getting hot but also the AMP per density of the Soda causes it to suck more AMPS in so i just to to tweak around a bit.

But happy :) it's working.

B.T.W i did grind every cell but still that didn't change anything it's the neg pos to far spaced apart, i guess as you say more volts and amps would get it going but my aim is to run 12 Volt battery bank! (author)Jaffasoft2011-03-19

I am glad you got this running, the sell looks really cool and that is really good output.

Jaffasoft (author)jj.inc2011-03-20

Yeah, thanks for the info. I followed your info and no other as it was a great digest of information more intelligent then i am.

I would never achieve anything without such ppl sharing there bright thoughts. Thanks a lot!!!

P.S. I will run this in my car next week.

Actually i meant Stainless Steal plates not Aluminum.

Jaffasoft (author)Jaffasoft2011-03-17

Just made an interesting observation.

I turned the cell upside down while still connected by chance to begin drain empty the distilled water and soda to add some salt instead then i noticed it was producing hydrogen bubbling only in the small area just around the larger 10ml thick holes where it was drilled right through i also had to angle grind the bevel edges around the hole after drilling to get them smooth.

So could it be that the plates are coated with something other then stainless steal and once gridded it is stainless steal below? (author)Jaffasoft2011-03-17

I think your simplest solution right now is take your plates and see if they conduct electricity. The metal doesn't matter, we just use aluminum and stainless steel because it is not corroded by the process. From what it sounds like you may need to grind your plates down. I also have done some more research and need to do a follow up of this. One of the better wiring patterns is Pos-neutral-neutral-neutral-ground-neutral-neutral-neutral-pos. either that or something close that divides evenly into your number of plates. I actually learned that you should probably have between 2 and 4 neutral plates instead of the whole stack.
If you have a port on both sides I bet that the electricity flows from around the hole through the hose to the other hole which also could explain the bubbles around the hole. I also may recommend lye for an electrolyte, it is much better than baking soda and salt. I also don't recommend aluminum. I am not sure if it is just me but my rods have been corroded down to nearly nothing in my $100 cell that produces just like yours. Thanks for your interest in my post, I like to help people as best I can. You have a very nice cell from what I can tell, thanks for telling me about the washing machine, I am going to the dump soon to look around.
MY BEST advice is to grind down each plate and then try it, if that doesn't work I guess I may have to ask for a video of the whole thing.

Before you race out to the Tip fridge & washing machine repair shops out in Industrial areas often have them out the back and can be picked up even cheaper then the Tip! That's where i got mine and a couple of fridges (for smoke house, hot water storage and heat duct encapsulation insulation, food dehydrator. The radiator will make an excellent cooler for a cell but i haven't got that far yet.

I'm not sure on how to test conductivity of the plates? but will try the grinding of them soon. Goal is to use this in a shipping container unit as cooking and who knows it may run a Sterling engine or something but the goal is to use 12 Volt regular car batteries or a 12 Volt source and least expense as possible.

I don't recommend using the salt as i immediately noticed rust appear across the entire plate surface and the water turned black from the black die in the gaskets. Not sure what the gaskets are made of but some sort of rubber. Just using Soda for now to test as it's cheap but not sure of where the other stuff is.

I have a heap of batteries i got from the Tip that are still good and have 5 connected up in series on 12Volt DC i think that would have increased the AMPS they are 12V x 36 AMP Hr batteries each so i will try that connected next. But first will grind each plate.

Thanks for your ideas and reply and helping! How is a 'ground' plate make effective? (author)Jaffasoft2011-03-18

I will go in order through your post.
To test the conductivity you can simply use a meter on two points of your plates, or you can see if a small 9v battery will spark when you make contact and slowly pull away. This shipping container sounds interesting but, what exactly do you want to do?

Yea, Salt is bad, I am now out of rod in my cell because I just used two rods in the top of a bucket.

12v DC batteries in a series actually increase volts so you have probably about 60 volts.

The ground plate I am not sure about but here is a link to my new powerpoint that elaborates more on neutral plates and wiring.

Building a 100% Eco friendly shipping container unit that can be lived in. It will have an outside (attached) 4x 4 mtr sun room for Aquaponics growing fish and vegetables in a Eco system.

The shipping container concept is to create a fully self sustainable place that can be transported and put anywhere and all you will need is to add or collect water and sunlight to make electricity to run it and live in it. Australia is very sun friendly so anywhere most places in Australia it would work.

So just lots of experimenting and thing going on as the project is a slow one. I have bought the container and began on all sort of little projects around it i.e experimenting with hydrogen to see what can be done with it.

I really just wanted to do the hydrogen cell because i have been cooking eggs that my chickens lay in an 240 Volt electric fry pan and want to take advantage of free way to cook it. I want to turn the grid power off soon.

I think i made a mistake with the batteries each ones neg connects to the next ones neg so they r ending up all 12Volt. Must be parallel I'm doing it?

Conductivity must be working as it's generating tonnes of Hydrogen now and that's only half the plates working.

Now that it's working i will tweak it add more cells, get stainless steal bolts, proper electrolytic and connect more negs and positives along the plates and possibly add cooling convection radiator and sell fulling system.

Have a video to upload for you of it. (author)Jaffasoft2011-03-18

Damn, that is a good looking cell, once you get it up and going you will have a lot of output. I just bought a bridge rectifier to run mine, 250v 6 amp, even though I would have preferred 150v 8 amp, they didn't have one.

Have you heard of a PMW being used, if you don't wan't to deal with that kind of money I recommend you turn your household AC to DC, it is almost the square wave in PMWs but it curves up and down, flat lines, and repeats. It will work very well I hope and I am exited, good luck with hour cell.

I have followed this well written instructable all week now once connecting the neg and pos it produces Niltch, nothing, not a bubble.

What could be wrong? I washed each gasket and plate with white vinegar did NOT dry them and bolted everything together and put a couple teaspoons of Bicarbonate Soda (Baking Powder) in some distilled water and almost filled the cell. Each cell is separated with a 3ml thick gasket and all the bolts insulated with rubber hose so as they do not short on any plates.

I cut the aluminum plates from a clothes dryer, it's nice shiny new looking .8 ml or so plate thickness at guess.

I pretty much built it to spec only difference was i cross hatch sanded the plate surfaces and used more bolts around it to secure it, each plate was around 200ml by 160ml and stands upright. One lower hole in each plate stagered and one 10ml whole going right through the top.

Disappointing i don't see why it's gone wrong? I connected one far side plate as the neg to a 12Volt regular car battery and the other side far plate as a positive. Could it be the Aluminum that is not really the right aluminum??

You should make one of these. I've never heard of a dry cell before, I made a regular one once although it was very crude and barely worked. I have an idea of how it works by the Google Docs file you linked but wondering how you get water in it without leaking since it's not submerged in it's own container. (author)Scatmanbrandt2011-01-18

Each plate has a non-conductive (like rubber) seal all the way around the outside, this allows it not to leak or short out. Each plate then has holes that allow the water to flow in on the bottom, then the one on top to let the gas through. A simple plastic hose attachment on the side is where the water goes in. I do plan on building one, but I just blew 100 dollars on a submerged one that doesn't work at all so it may be a while.

Scatmanbrandt (author)jj.inc2011-01-18

Ok, that makes sense. One last thing though; how do you get the current into the water, Is one half positively charged and the other negative? I may try making one myself when I get the cash, sounds like it would work better then a submerged one. (author)Scatmanbrandt2011-02-11

I just found a great video of a dry cell, this guy has a bunch of information. I would recommend watching all of his videos, but this one gives some of the better info. (author)Scatmanbrandt2011-01-19

Yep, the cell in that link I gave you has a water in/gas out port in the same thing, definitely wouldn't recommended that, you will not have any control over your water level and you will have to refill it constantly. (author)Scatmanbrandt2011-01-19

Yea, you charge a one plate on each end, the plates between are 90% positive, then 80% and so on, those percentages are based on a 10 plate cell. Yea, they are much better than a regular submerged one, look here before you make on, the designs are great, although I don't see them drill a hole for liquid.
The first picture you see has separation between the plates, that is just to resemble the gas hole I discovered after a while. I am not sure how this design gets the water in, but I hope it is not through the upper holes, If it is I would add lower ones to.
