Improving A Hydrogen Generator

[DeliciousDeBlair]

One major drawback we experienced with high volume gas generation was bubble adhesion.

To obtain and maintain efficiency, not only do you need the surface area, but also a way to prevent the bubbles from remaining adhered to their surfaces, which, unfortunately, begins choking out the flow of water and electrolyte, causing production to drop off.

Your video on the brown gas generator was very interesting. I am from Bangladesh, a predominantly agriculture based economy, urea is abundant and cheap here. Farmers need electricity for irrigation purpose and more and more are trying to use solar but the cost of panel and battery is still prohibitive. I looked around to see if the h2 gas generated can be used a fuel source, of course they can be used in ICE or h2 fuel cell but i was looking for something cheaper and simpler(no moving parts). I came across Ni-h2 batteries/fuel cells used in old spacecrafts however it seems it's a pressurised system. I also found some fuel cell design uses heat rather than precious/exotic metal as catalyst. That looked promising because sunlight is available through out the year.But still, their manufacturing seemed intricate. I know you have a lot of ideas floating inside your mind, but please give some thoughts on heat/solar h2 fuel cell designs without exotic materials. As always I am absolutely amazed at your curiosity, knowledge and dedication.

When I first saw it, I thought you'd put it all in graphene ink!
Am I right in thinking that the stainless steel mesh will eventually dissolve on one side and get thicker on the other, if so, do you just reverse the electrodes periodically?

One idea I had years ago was a hybrid gas/electric oven, which burned hydrogen to cook, but you produced the hydrogen on site with electricitty. So you'd have the advantages of a flame stove, but it could run on electricity.

Although you have separated the anode and cathode into chambers using that bridge, there is a still a major problem. Collecting that hydrogen is very difficult because you cannot have ANY kind of back pressure on the gas coming out of the chamber or else it will force the water down, through the bridge and out of the anode side. You MIGHT be able to bubble the hydrogen though shallow water and collect it in a very small container using water displacement. The best way to achieve gas separation is PEM technology. You have a rigid solid membrane between the two half-cells and you can exert a great deal of pressure on either side (or both) to fill a balloon or even compress the gas into a cylinder to some degree (no pump needed!) A straight Nafion barrier between the hall cells would suffice to separating the gases and allowing collection, but then you sill need an electrolyte (that won't damage the Nafion). And, of course, a PEM cell (that also uses the Nafion) but has the platinum and iridium electrodes pressed right up against the membrane (MEA), is the ultimate solution and requires no electrolyte (the Nafion acts as the mechanical barrier AND electrolyte in this cell).

as a child we used to charge lorry batteries and put milk bottles inverted on top of cells, then put bottles on ground and ignite them a lovely blue flame and a bang.
Even then we knew that oxygen improved the burn, so one can assume that oxygen would assist the burning of hydrogen thus increasing energy being produced.

Try using square containers instead of round, and then put a SS plate in each container. Then connect the containers together as close as possible - yours are 1" apart. The plates should be millimeters apart, but separated by the container walls.. Get them closer so the plates within both containers react with one another (not just the plates in the same container).

Mister Murray-Smith, Thank You, Thank You for knowledge you giving to us and passion for science you share.

[PitchUpCampsiteReviews]

Absolutely loved the video.
HHO mini torch, wire coat hanger, tiny piece of precious metals (platinum) out of a car catalytic convertor.
Hypersensitive solar panels, I can't bring them to the top of my head right now but I think they might have been photovoltaic cells.
I saw it on a channel a couple of years a go but the channel disappeared but once the platinum begun to glow it allowed thy guy to turn his torch right down to next to nothing but the actual platinum looked like it was burning as bright as the sun.


Fantastic work you're doing and I hope what I've written drives your curiosity to see what can be potentially done with it.
The wire coat hanger is to suspend the platinum on.
When he surrounded it with the solar sensitive cells he used a plastic fish bowl because it didn't give of any significant thermal energy to the surrounding area.
Have a great day.

What brand of paste comes with the clear container you are using Robert ?? Nice work too.

[FuhrChris]

The interesting question is would you try for liquid air batteries in a small enough system for one shop/house,
Or
A hydrogen storage system?

[Mr_Blinky]

Brilliant idea using two jars to separate the gasses at source. I think you could go further and make it more efficient by putting many tubes between so the ions have line of sight from anode to cathode, or vice versa. In order to make sure the gasses did not mix half way up the jar (where there are more tubes) you could use slightly U shaped connecting tubes so that rising gasses were diverted from the center of the connecting tube. That would give much more liquid contact, thus increasing ion transfer. It sounds confusing trying to write it. If you don't understand let me know and I'll get a diagram to you.

The nitrogen could be converted into nitric acid by diverting it to a tall column containing solar power spark apparatus and have the dilute nitric acid condense and collected at the bottom of the column.

[ryanbrown]

How are you handling the creation of hexavalent coming from the stainless steel? I thought that was a show stopper for using stainless in an electrolysis cell.

[wateristhefuelnotfossil]

It would certainly be a luxury item if let’s say a rolls Royce was equipped with such a separator wet cell and hydrogen was fed to the fuel injection air intake and oxygen was sent to the interior of the vehicle as a way of fresh air full of oxygen for the occupants to enjoy while windows are all pulled up securely to protect the occupants from outside pollution

Presumably, you will have to top up the urea concentration periodically. So what is the best method for monitoring concentration? Will it be the increase in Oxygen production, or the reduction of Nitrogen at the second electrode? Or is there a simple way of measuring urea concentration? Thanks Robert.

[Gwydion]

Thanks Robert.👍 I also was about to ask for gas separation, but already knew how to alter the construction.
Nevertheless, fast as a flash you came up with such improvement, plus even more.⚡😄
I'm curious about your next brilliant mental sparks, jumping right to your next upload. 🤓
Difficult to keep up with all of these inspiring contributions from my subscribed channels... 🤩

[TheWingnut]

You never cease to amaze Robert....have you done experimentation using a high frequency, high voltage. low current power source?

[Rickwaves]

i would like to see the unit with the hedge bridge in action n can i put the hedge bridge at the bottom on 90's n what is the production volume of H and its voltage .... please respond

[rogerbarton]

Is the black coloration caused by particles of carbon breaking away from the felt? Years ago I built an electrolysis cell using carbon electrodes and they didn't last very long at all.

An easier construction would be to have a vertical plastic pipe containing the hydrogen electrode suspended in a bowl of electrolyte, this pipe would have a stopped end on the top to which you can attach the take-off pipe, as per the original video. The other electrode would be suspended in the electrolyte as before.
