Hydrogen Electrolyizer

Ok here is the basic plan / idea, remember that we haven't try this yet, it's just an idea.

Homemade hydrogen eletrolysis design plan

How it works.....

To start with, all the taps are off and the water tank is filled. Then we turn on the first tap next to the water tank, and the water flows out to fill the bottom tube and moves up the oxygen tube to reach the same height as the water in the water tank.

Then you turn the gas tap until water comes out, filling up gas tank with water. Once the water come out turn off the gas tap and the 'system should be ready. Now you plug in your terminals and the gas can start bubbling away. The oxygen will flow out of the system and the hydrogen will build up in the tank. When you turn the gas tap, the pressure of the water in the main tank pushes the gas out.

    Things to note:
  • U-bend to protect the tank from sediment flowing backwards.
  • Terminals on removable caps for maintenance and to change the terminals if needed.
  • Tap at end to flush out any sediment build up.
  • You may want a float switch on the gas tap to stop water flowing out if you use up all the gas.

What do you think?

True it is not very efficient method however, if someone has excess power and is using a diversion dump with some changes this might work.

As the hydrogen builds up in the tank it is going to displace the water in the oxygen pipe and the tank. Just make sure you have enough space at the top of these to accommodate the extra water.

hydrogen is a extremely explosive gas which is extremely dangerous. If you intend to use it for cooking, etc. I suggest you write out your will now. Moreover, electrolysis is a very inefficient process-- the amount of energy required to split a molecule of water is enormous. As someone mentioned above, a batery bank or connection to the grid system is a much better option. Joseph Ockerse.

You do not need to add sulphuric acid. If you did this you would be making a battery in the tank (if you used different metal for the wire). I have seen it done with plain water and electricity. Water is not a conductor contrary to popular belief it is the imparities in the water that makes it conductive. If you won?t this to work really well add a little baking soda. I don't know why baking soda works so well but that is what we did in high school science class. Also store the Oxygen and work on a use for it instead of letting it go to waste. I used to do this and use the oxygen when I was shipping fish.

making your own hydrogen? Don't let Bush see it, he'll have you arested and renditioned to Egypt for being a terrorist. Have you done the maths? How many KWh in from a PV panel for gas converted back to electricity via fuel cell I assume. It may be more efficient charging a battery bank.

Putting two wires + and - will just short circuit the battery.

I think it is a good idea. The primary thing that needs to be worked out is pressure regulation. Once the H begins to fill the gas tank the water and the gass will begin to pressurize. Which is what would want. However, eventually the water pressure would become greater than than the input water tank and we might begin to see the water back flow. Either up the Oxygen outlet or back into the main tank. To fix this one could do a few things like pressurize the input tank and put in back flow valves. If not then perhaps put a presure release valve ont the hydrogen tank to release the presure before it causes backflow so that the hydrogen is stored in a secondary holding tank or used. Otherwise we end up with a fancy hydrolic pump.

I believe as long as you use a platinum catalyst you don't need to add sulphuric acid to the water.

your terminals ..what material are they made?... escuse my english

man.... no oxigen... no fames goeing in to the tank...

This isn't an great idea because of the enormous big tank needed for the Hydrogen. The H has to be compressed to get an acceptable Energy-amount in the tank. For small energy storage up to a few 1000Wh lead acid battery are much more practical. mfg Esko

I would invert the sediment trap and add a cleanout in the bottom. That way no gasses could build up in the top of the trap.

the water needs to be mixed with sulphuric acid for electrolosis to take place

It may polute your water tank so I would make the tank single use. ie... don't drink from it. DesM

You should also add a flashback arrestor to stop flames going into the tank.
