I hope you will update this video after few weeks/months of testing. Can you please give us links to the membrane and oxygen detector you are using? If I remember correctly you did say something about hydrogen detector - how it's going? Any news about it? DIYself hydrogen detector would be nice, cause those in stores are quite expensive... Anyway GREAT project, and some amazing ideas!
I used the same cloth material as (swim shorts) for the membrane. Polly nylon or polyester I believe this material is very chemically resistive. And will not let air through easily as well. Like when you jump into the pool and have a big bubble in your shorts.
Right ok, I've watched this now. Brilliant video, brilliantly explained I will try this myself and you have a new subscriber (me). If you're in the UK, pm me your details and I will order you the graphite sheet to play with. Graphite and neoprene rubber will stop this and potentially be more efficient, would love to see someone like you try it, and decide if it's good or not, I have found some interesting results. Credentials? I'm a massive massive nerd, watched many lectures and have started to design my own hydrogen boilers. Look forward to hearing from you 😉
Hello and a big congratulations for your tutorial they are very interesting. can you tell me what kind of membrane you use and where you buy them? thank you very much 😊
Holy shit. I just watched a video of yours and checked the channel how the fuck have I not found you yet my god your channel is amazing I can't wait to watch it all... Love the way you explain things man nice 1
@@johnking6188 I did watch "REPLACING GAS WITH HYDROGEN" and we have similar goal, cap the energy at day STORE IT, and release later on (at night for example), you have very nice setup, keep it up! I also want to compress hydrogen (non liquid state) and use it a a fuel in some engines. It would be nice to have a car/motor on hydrogen.
@spamator12 I have just started squashing the hydrogen into metal hydride in a home made tank. I'll post when I have data and footage. I agree, storage is the problem. Hopefully hydride in the mix offers solutions.
Sir cant we use your split cell design in your #3 video by stacking many split cells together with neutral plates and pipes out of each hydrogen and oxygen chambers . does it have drawbacks ? or why you chose not to use the chamber design stacking instead of
I'm looking to build the most cost effective hydrogen generator for an rc airship, would this be the best method for aluminum plates instead of copper? Not entirely sure how well it would electroplate and how well it would avoid corroding.
Very interesting thinking outside box. Have question on comparison with steel that people scratch to get. More hydrogen. Can you test against against for results. The cost savings on yours would be considerable. Life expectency is also a question
That's great I hope it works great for you for a very long time. You can find stainless steel sheet free if you can find someone throwing away certain restaurant equipment,it's a lot of work getting it all apart but it beats having to buy it, I salvaged some once years ago but sold it because I needed the money for tobacco, thankfully I have manage to beat that habit/addiction. I'm glad to see you getting that back together.
@@TheDIYScienceGuy titanium is used for electrodes in PEM generators as it doesn't oxidise causing problems for the ruthenium iridium catalyst. We build them and they seem to conduct electricity just fine.
That is a good question. It is definitely something I want to do, but I have so little time and so many other projects. But I think next year when I have the shed all up and running, I will continue the project. Thanks for sticking around!
Respect of colleagues. If you remember, I asked you for advice on the choice of membrane material for separating hydrogen and oxygen. I'll confess without any secrets, I chose retex membrane material, thickness 300 um, and the electrolyzer separated hydrogen 100% well, but after 200 working hours of electrolysis it happens that occasionally a mixture of H2/O2 comes out of the hydrogen port, which is not good. I can't clarify what it is about... ?
@@TheDIYScienceGuy I can't rationalize things, why does my dry cell electrolyzer sometimes separate H2 and O2 well, but sometimes it doesn't? I inserted a polyprolene cloth material as a membrane.
Hello, can someone please help me? I'm currently trying to rebuild the generator, but I think I made a mistake with buying the membrane. I bought PolyPropilen 150g/m2, which is actually for weed control. Unfortunately, the material is completely waterproof and doesn't conduct electricity. 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.
Hi, the material needs to be permeable to water so the current can flow through it. This is what I use now: www.amazon.com/Kimberly-Clark-33560-Polypropylene-Kimtech-Surface/dp/B00UBGXXS4 hope it helps!
Very well made electrolyser and quality of the process is perfect! To check if there is any oxygen in hydrogen just make a spark inside hydrogen sample balloon (if there is no flame after spark inside ballon with a sample then that means no oxygen in a sample). Regards!
@@TheDIYScienceGuy of course safety is most important so once you fill up a small sample baloon from the main h2 storage container then do the test in safe place far from the generator and preferrably outdoors. You can use a gas cooker spark igniter or somethin like that. Then for comparison add some air to the sample baloon to see what happens when oxygen is mixed in sample.
@@TheDIYScienceGuy That (the soap bubble test which is known as the pop test) is completely different to what Kapalek84 is suggesting - the spark occurs inside the balloon without letting any air in and is therefore used in the hydrogen to test for the presence of oxygen, if no oxygen, then no ignition of any kind. You are looking for a very small amount of mixing of O2 and H2, so if you were to periodically spark the H2 gas and use a microphone to listen for tiny explosions you will have a continuous testing process. This will test for oxygen (or chlorine) in the Hydrogen from about 4-74% concentrated. This is a fairly high contaminant level in the H2 so the spark test is not particularly sensitive. If that resolution is acceptable, then, although sparking sounds ultra dangerous, if you sample and isolate the gas and provide suitable safety features, then it is relatively safe. I would personally pipe the O2 a long way away and same with the H2 container - in opposite directions! The idea is to isolate the testing sample in a small, thin glass tube with synced input/output valves, a pressure relief valve and embedded electrodes. A glass blower can build this for you. If the contaminant is small, then the microphone will pick up a pop and will vent through a pressure valve which can just be a simple spring on a stopper arrangement. The spark comes from two wires that are very close to each other in the tube with a suitable high voltage from a pulsed power supply. I suspect the wires will need to be replaced often since H2 is quite corrosive, so embed these in a suitable stopper that can be removed and replaced.

Hello. I got a low cost poreless ionic membrane but p acid solution. Membrane electrolyser is OK. But I have to solve negative electrode wear. For alkaline solutions, there are those used in PEM cells, but they are very expensive. I am trying solution to use nickel and alkaline solution. I liked your lab. Good luck.
ha just a reminder the air line must be above the air intake to get read of the bad gas. your not venting bad air the way you have it in the video. please stay safe we all need you alive.
Have you ever considered using graphene foil as the electroplate for hydroxide-oxygen generation? Otherwise awesome workmanship and video! Thank you for sharing!
I've test with graphite rods from zinc-carbon "Heavy Duty" batteries in the past and the anodes would dissolve and the gas produced there wouldn't burn, leading me to believe it was creating CO2
@@chadw8164 hmmm that's an interesting problem. I know the idea of graphite foil is from Robert Murray-Smith(youtube name) but lookin at the research paper he refers to it does talk about the issue of high concentrations of electrolight destroys the anode side as you say. He also uses Urea as his electrolight.nit sure how that changes the corrosion. Wish he talked more about it www.researchgate.net/publication/273806853_A_Systematic_Study_on_Electrolytic_Production_of_Hydrogen_Gas_by_Using_Graphite_as_Electrode
Well I've been building a new workspace over the past year. The generator has been running the amount of hours I mentioned in the video (don't remember how much it was) in a few Months I will plate more electrodes and build up the generator to its big size.
can you use baking soda so that the salt doesnt create chlorine gas from the electrolysis. now i see you have ventilation but you said it was for the nickel
I use vinegar and a small bit of salt. I don't think it's creating a dangerous amount of chlorine gas. The nickle vapor is much more of a "problem". Backing soda might react with vinegar creating sodium acetate and Co2 gas. But thanks for the suggestion! 👍
@@TheDIYScienceGuy It's OK now. Alkaline electrolyzer with separation of hydrogen and oxygen, has been working perfectly for a full year using a polypropylene cloth, thank you for the advice. Finally, thanks to you, I found the right material for alkaline electrolyzer membranes :)😁
Patience my friend. Do you follow me on facebook or instagram? Because there you can see what I'm currently working on. Or you can become a Patreon for more extra special behind the scenes stuff.
@@TheDIYScienceGuy are the holes made to keep it together the same size and what is the spacing for those? Also I thought according to an earlier comment I saw the copper plates were 0.8mm thick?
@@TheDIYScienceGuy sorry about the fact I am asking so many questions. I am making a cad model. Also how far away are the water inlet and gas outlet holes including the width of holes from the plate?
Interesting video thanks, however, for the uninitiated, NEVER double up gaskets, not even using gaskets of rubber insertion and a secondary layer of silicone, use one or the other but never both together ....for they are dissimilar materials, wi different expansion and contraction ratios and WILL seperate and LEAK ... In due time... If no the day then some day soon.... So... I really appreciate your video... Thom in Scotland.
something tells me the reason the plating was happening only close to the anode was bc of insufficient current i think a current source as opposed to a tension/voltage source would be better, but i'm no expert just thought it's bc ions and charges are mostly neutralized closer to the contact, and saturating it with more charge than the electrolyte capacity would make platting even
@@TheDIYScienceGuy I am a bit confused why the resistance would be too high. These same strips are used for lithium batteries and the resistance is only 4x copper. The currents you are pushing are no where near causing this resistance to be significant, and you even mention you did not measure the difference.
@@TheDIYScienceGuy why not make it thicker? You can use 2mm of nickel plates instead?´of .5mm copper . I think you loose a lot more in the wiring than you would loose even in a .5mm nickel plate since the plate has a huge cross of 125mm² with a resistance like a 30mm² copper AWG-2 cable
In your next video; check the audio volume before your publish it. This video has very poor audio quality. I wonder why it did not catch your attention.
A natural pate products H2 on one side and O2 on the other, which means that you would have an H2 O2 mixture again. The membrane must be non conductive but permeable for the electeolite.
You mean by cooling down the gasses so the oxygen would condence out of it? Yes, that would work. Just a bit impractical but could be usefull for extra purification. Good thinking! 👍
how will you capture the hydrogen and compress it into tanks to make it useful? this would be great if you could do this and turn a wankel rotary engine into a hydrogen electric generator
how would you reverse plate a diamond layer on a steel plate as this Indian Nield Tyson suggests? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wAX8I35xw1o.html
How thick and how large a squares are the plates you used? I am thinking of 12" x 12" square plates between 20 to 16 gauge thick. Are you being able to produce more hydrogen with the more efficient plates? How well is the Nickel plating holding up? Thanks, I need to replace my natural gas supplier with something because the new supplier jacked the price up double or more , I figure their intention is to do use like the did Europe, their goal is to exterminate 90% of the worlds population in a such a sneaky manner and make out like it was an accident.
@@TheDIYScienceGuy the plates are 0.5cm or 0.5mm? 0.5mm is thin and would make it a lot cheaper to build but 0.5 cm is very thick and very expensive. Is it the greater the surface area the greater the volume of gas it will produce?Thanks
