[@angelorondini5835]

What is the membrane for?

[@TheDIYScienceGuy]

To separate the hydrogen and oxygen.

[@kreynolds1123]

How hydrophilic a separator is as well as having small pore size helps prevent gas bubbles from crossing. Keeping a low rate of production helps the bubbles form larger bubbles before separating from the plate and the larger bubbles have a harder time pushing through the separator. I always wonder how well the tight weave on my wife's nylon stockings would work. ssshhhh dont tell her.

[@alfredharrison597]

Clay from clay pots that arent glazed work great in this way.

[@kreynolds1123]

@@alfredharrison597 my other interest/hobby is electronics, so when I think about how to understand an electrolysis setup and considering that it is an electrical circuit I tend to mash the two together, modeling an HHO cell for better understanding using standard idealized electronic components. To that end, and considering current doesn't flow unless voltages exceed what is called a zener voltage, then electrolysis is easily modeled with a resistor and zener diode in series with the zener diode having a zener voltage of 1.24v. Tripling plate area is like three resistors in parallel whoes resistance=1/(1/r+1/r+1/r) were r is the resistance of unit plate area. Adding a clay pot separator slows down current exactly like another resistor in serries and current through a resistor generates heat, where as over time current through our model zener diode = chemical work done. That is time×i×1.24v=chemical energy. So in the name of efficency we try to minimize the effective resistance while sustaining a desired hydrogen and oxygen production. On the other hand clay does a fair job of keeping weak analytes and catholytes seperate under an electric current through the resistance of ion flow through a clay pot. So a clay pot might be a fair choice for making weak analytes and catholites when they are the desired product. For simple and efficent gas seperation, a hydrophilic seperator like nylon allows ions to easily through a nylon mesh with little resistance while the nylon holding water to its surface when combined with water's surface tension helps prevent gas bubble crossing the hydrophilic seperator. I'm not certain about the purity though and i concede that maybe despite nylon mesh being hydrophilic, might not sustain sufficent gas seperation purity, and that maybe clay would.

This is great! And I like the music :) I will try to build something similar later on. BTW - shouldn't membrane be electrical resistant? Plates are charge carriers (through water with NaOH or KOH addition) so electrolysis can work (+/-) on them. Do I understand that correctly?

[@TheDIYScienceGuy]

Thanks! No the membrane need to be electrically conductive otherwise there wouldn't run any current and because it consists of fibers with water in between, fore the current it's like the membrane isn't even there, so no +/- change.

[@spamator12]

​@@TheDIYScienceGuy wow I feel like being in school back again :) So the membrane must be conductive but... actually without generating any current on it self... Yea it somehow make sense but can be confused that's why I asked. Thanks for fast answer!

[@TheDIYScienceGuy]

Well not generating but conducting. When the electrons go trough the solution than nothing changes in respect to how the electrons move, but when the electrons go from being conducted by the solution to being conducted by a metal plate than it creates a +/- side. And because not the fibers but the solution in between the fibers is conductive, nothing changes.

[@petergoestohollywood382]

spamator12 spamator12 the Membrane is only there to hold the gases separate. We want as little electrical resistant as possible because we don’t want charges to build up at the membrane and want as little „energy loss“ as possible. Maybe imagine an air filter. You would like to have a good air flow rate but filter out any particles simultaneously.

[@patri0t1776]

@@TheDIYScienceGuy I think you mean "permeable" not conducting. Nylon, polyester and polypropylene are dielectric. They don't conduct. The NaOH or KOH solution permeates through, and that is where the conductivity between the plates follows. If you used a conductive mesh/ membrane it would act like a neutral plate, regardless of its permeability, and change the function of the cell. The gas membrane absolutely has to be non conductive. Good cell and demo. Keep up the awesome work. 😁

So when I apply a multimeter, there is no resistance (Ohm) measurable. Can this even work like this? Unfortunately, I have very little knowledge, so I would appreciate scientific answers. It would also be great if someone could provide an Amazon link to a more suitable membrane material (in the EU). Thank you very much in advance.

your plates are to far apart. this will make the amperage you require to make this work really high...high amperage will cause the heating you are having issues with. melting plastic and all. Voltage doesn't cause heat. Amps cause heat loss. by putting the plates closer you will be able to get closer to the 11-12 volts required to optimize the gas bubbles vigorously forming on the surface of the plates.. the spacing of the plates dictates the amperage required. your sepperator is great and will still work. think about ordering some very fine micron screen from ebay. like the screen used for silk screening.. Great video ,) Forever making.

[@TheDIYScienceGuy]

Thanks!

[@wiktoriaslominska8078]

Actually, the further the electrodes are apart from should reduce the current at a given voltage. Also both hydrogen and oxygen are generated on each electrode so unless you let the ions travel in your electlolyte to the electrode with opposite charge, you won't actually separate them, and once they form gas molecules and float to the surface you get pretty much a bomb. Very dangerous stuff

[@kreynolds1123]

"Better" is ill defined. One can get more production if they run more amps. One can get more efficent production if they lower the voltage. Dry cells are nice if you use neutral plates allowing you to work with higher volt power supplies. Wet cells allow you to use more of the plate surface area but need voltages that are not as flexible in voltages supplied. Dry cell with a membrane is needed if you want to keep the hydrogen separate from the oxygen. Wet cell is less complicated in its construction.

@@TheDIYScienceGuy my thoughts, with non conductive water if your probe points are practically touching, you barely get something at all instead of absolutely nothing... correct?... with the normal/average cell the closer the plates the better preformance, but if you get them too close the gas won't escape? So dont use a plate, use a needle, and a skinny tube with needle in the center on the ends. If the mixture is thick enough you would have plenty of carbon particles touching each other directly, and plenty of them with microscopic gaps of water in between the carbon particles! Recently learned that it's just the basics of any conductive surface... So carbon particle - microscopic layer (boundary) of water - carbon particle... the smallest hho generator ever, but in a cluster as a thicker slurry. And the bubbles won't be resisted. With this setup no way to separate the gases (via membrane). But the carbon would never get consumed correct? If this works? And would it ever need cleaning if used pure distilled water?

@@davidprock904 i am maybe 90% certain that it would not work that way. Lets start with.... 1) In an ionic solution current wont flow until you have a voltage above water's break down voltage. Using distilled water with carbon nano particles in a carbon slurry will start conducting at a much lower voltage, and because a voltage develops across a resistor when you push current through, you'll never have eneough voltage between two particles to electrolitically reduce water. Using a third electrode to sense voltages, youll find that From one electrode to the next, youll have a continous voltage gradient drop. Another way to see this is to see it like an electric circuit. Say we have a cell fed 3.24v and there is 10 amps flowing through it. Electrolisys may be roughly and simply modeled as a resistor and a 1.24v zeiner diode in serries. The resistor's value is a function of electrolyte type and concentartion, and is generally inversely proportional to both plate surface area, and the distance between plates, Bubbles block current between the plates and thus increases the resistance too. Now if our resistor is modeld at 0.2 ohms, with 10 amps flowing through it 2v is developed across the resistor. Consequently 10 amps × 2v means 20 watts of power is making waste heat. Now the 1.24v zeiner diode adjust its resistance to alwase have 1.24v across it in a resistor zeiner diode series, so with 10 amps flow through it, you get 10amp × 1.24v =12.4watts of heat in a real zeiner diode, but our zeiner diode represents the breaking apart of water storing 12.4 watt every second as 12.4 joules of chemical energy. Now lets model a carbon slurry. You have a bunch of little resistors in a serries and parallel network that is In serries and in parallel with with the zeiner diode such that the more carbon you add, the more current is shunted, bypassing the zeiner diode. 2) ions in water ionize water molecules into H+ and OH- ions. Crushed carbon does not ionize the water. 3) He is trying to keep hydrogen and oxygen in two seperate half cells. Even if a carbon slurry generated H2 and O2 at the surfaces of carbon nano particles as you though, it's impossible to keep the H2 and O2 separate.

You can use Stainless steel, but use a type that you know that it has a high Nickel content and run the cell with a relativley low current . Nickel is waaay more resistant than Cromium in a alkaline environment , so it is quite resistant.

[@santiagocortez9554]

Can this be powered with sollar cells? If so what do I need besides solar cells?

[@TheDIYScienceGuy]

Yes it can be. You can connect it directly, the only other thing you need is..... the sun 😉

[@santiagocortez9554]

@@TheDIYScienceGuy it can also do the reverse right??? Like if u feed it with hydrogen and oxygen, you can then connect to the plates like u would in a normal battery

[@TheDIYScienceGuy]

Not this one but I'm working on one that can.

[@Xapiro]

Hi. Is hydrogen always generated at the negative pole?

[@TheDIYScienceGuy]

Yes.

[@Xapiro]

@@TheDIYScienceGuy Hi. What would be the most efficient cell? Those with two separate negative and positive poles isolated from each other, or those with neutral plates?

[@TheDIYScienceGuy]

With neutral plates you don't need a 2 Volt 425 Amp transformer, you can just use a 12 Volt 70 Amp transformer which is easier.

[@Mark300win]

Is it polyster or nylon

[@TheDIYScienceGuy]

The label says nylon. But could also be polyester. A polyester tablecloth would work to.

[@miguelchacon2717]

But would it produce electricity if you insert oxygen and hydrogen and connect the two plates

[@TheDIYScienceGuy]

No that would require a different construction and a catalist.

[@nicholassontag4312]

What's the benefit of using sodium hydroxide instead of another electrolyte like sodium chloride? production of chlorine gas?

[@TheDIYScienceGuy]

Yes chlorine is a big problem. It's bad for your health and it corrodes the anode very fast.

[@thebuttorh]

@@TheDIYScienceGuy how about pottasium carbonate?

[@TheDIYScienceGuy]

Also works but NaOH and KOH are best.

Can you make H2 separation using PEM technology please

[@TheDIYScienceGuy]

Maybe I will do that in the future. Thanks for the suggestion! 👍

[@klab3929]

So can't you also cool down the gasses and then seperate it through magnets since liquid oxygen is ferromagnetic?

[@TheDIYScienceGuy]

Yes that is possible. You can also make fine bubbles and let them go past a magnet apparantly.

How about the oxygen? I like the concept and such but on our study, we need to obtain the oxygen gas :0

[@TheDIYScienceGuy]

The oxygen flowes out of the other hose, and you can do what ever you want with it. What is your study about?

[@kaialegre4946]

The DIY Science Guy Ah we need to obtain the oxygen from water by splitting it from hydrogen, obviously. Since we cannot find any cheap and good semi-permeable membrane. Anyway, what kind of nylon did you used? Hezhez

[@TheDIYScienceGuy]

Just a nylon or polyester table cloth but it seems that polypropylene is the best option.

You can use nylon, polypropylene or polyester. Just go to a dollar store and by a table sheet and look at the label to now what material it is, and do some testing to se if it doesn't dissolve in sodium hydroxide.

[@angelorondini5835]

@@TheDIYScienceGuy do you need sodium dioxide or can you use any salt?

[@angelorondini5835]

Like normal kitchen salt (sodium chloride)

If you use sodium chloride you will produce chlorine gass as well, which is very toxic and it will corrode your anode very badly.

Hi is it possible to use an inverter to power the hho cell in the car or permanently wires battery charger in

[@TheDIYScienceGuy]

If it can generate enough amps than that wouldn't be a problem I think.

[@michelezamparini8976]

Che amperaggio deve avere ĺalimentatore?

[@TheDIYScienceGuy]

l'intensità della corrente è determinata dalla resistenza dell'elettrolita e dalla superficie degli elettrodi. mai applicare più di 2 volt.

i think the rip stop nylon doesnt allow water to flow through it not only gas? What nylon material did you use

[@TheDIYScienceGuy]

It's a tablecloth. No rip stop wouldn't work because it's water and air tight.

[@nIkOlA991ful1]

Hello my colleague, I beg you to tell me which material is this tablecloth, because yesterday I took a canvas 1 mm and I solved the problem of separating gases, but I have a new problem with the fast solution of the solution in the dark blue color, the material looks not resistant to alkaline electrolysis , now I'm looking for the ideal material ???

[@TheDIYScienceGuy]

My tablecloth is made from nylon or polyester.

[@nIkOlA991ful1]

Thanks for the reply of the friend, here I am using a material similar to your nylon blue color that I display in this piston, it is 1.5 mm thick and perfectly separates the gases, and I no longer have the problem that my nylon is rubbed in the cells. But there is a problem of another kind that the Sodium Hydroxide solution quickly blubber, and it becomes dark blue! Probably this material is in the process of electrolysis?

[@TheDIYScienceGuy]

Yes that hapend with mine to, I think that is what's going on.

Splitting water up results in two hydrogen and one oxygen atom. Hint: h2o. Fix the thumbnail lol

O imidiatly binds with an other O which forms O2 which is what comes out of the hose, that is why it says O2
