Linnard?s hydrogen on demand system without electricity !

[ResinRat2]

Hi nickle989,

Thanks for your input. I would say that if you have an idea of how to design a circuit that uses a load and charges a battery then please post a diagram of your idea. I would be very interested in building a circuit that looks like it might accomplish this. I will take your advice on using a lead-acid battery to be charged, unless you can show a circuit that would do this for a NiMah or NiCad battery. This is what I would really want.

As far as the plating of zinc goes, earlier in this thread Dingus Mungus shows a design that could be used for the replating of the zinc that goes along the lines you suggested: the idea of a connection at the bottom of the cell that would keep the flaked zinc in electrical contact with the system. This is a good idea; but I was hoping to use the electrical circuit to regenerate the zinc often enough so that only a thin layer would be replated at a time, that way it would be less likely to flake off. (That's my theory anyway.)

You should have no problem finding magnesium and silver colloids at health food stores, they are common items.

I tried to balance the system chemically earlier in this thread. I began to hurt the hydrogen production rate, and started to form a precipitate so the cell solubility was altered as well. I would be very interested to see if you can have better results. I am always open to suggestions and I hope you can have a breakthrough. Please post your results here so we can all see.

Hi Chris,

You are going to laugh but the way I have been weighing out my NaOH is by using a ruler with a round pencil taped to its bottom at the balance point with a dixie cup on each end of the ruler. When resting on a table it is balanced. Here is the trick. An American penny minted before 1982 weighs 3.1 grams (approx). A penny minted in 1982 and afterwards weighs 2.5 grams (approx). So I place 40grams/2.5grams per penny = 16 pennies in one cup and add enough NaOH to the other cup to balance. This is my home scale  . I don't have any fancy expensive Mettler balances as home. So I don't think I will be weighing my anode anytime soon.

I think initially I will be using the fuel cell to power a load. I have a small propeller motor I purchased with the fuel cell. I hope to show this running on the hydrogen cell as it is producing gas. In the future I hope to charge up batteries for zinc regeneration. One step at a time though.I also think your idea of using a stainless 316 electrode for zinc regeneration is a great idea to try. Let me know how it goes.

Also, could you tell me what adjustable DC power supply mramos suggested to you? I may be interested in that too.

I have noticed that I will need to order the right size hoses to fit the fuel cell, so results for me will be delayed for a bit. I am sorry, but I didn't know what I would need to hook these things together. I am learning as I go so have patience with me everyone.

Thanks for your interest.

Hey... A scale is a scale... LOL!

My current power supplies are 12V-2A, 9V-1.5A, and 5.6V-.65mA phone chargers.

With this PSU I should be able to determine the best voltage for Zn reduction.
(my current plating is fragile and loose... too much wattage I think)

I still need some solid zinc rods but I'm ordering from a new supplier this time.
Also I'm picking up some 5-10 mesh Tungsten carbide pellets or ingot. (<surface area)
Thanks for the best wishes, and the same goes to you in your PEM experiments.

I know we're close now,

Hi Everyone,

Well, there are a few conclusions I have arrived at over the last couple of days, and I must say it is a good thing I was delayed by needing to order hoses for the fuel cell. Even though my fancy glass reactor looks cool and I would love to use it with the fuel cell, I think the design will not work properly in this case. The reason for this is because I have been observing the reaction in the cell and even though it seems just hydrogen is being produced, I can see the gas on the zinc electrode slowly coming off, and gas bubbles also rising off the zinc precipitate on the bottom of the reactor. It is my understanding that oxygen entering the hydrogen side of the fuel cell will damage the cell and eventually cause it to no longer function. This tells me I need a completely new set-up to use a fuel cell with. I need to be sure the hydrogen and oxygen are not mixed. This is not possible in the present glass reactor.

Looking back in this thread, Dingus Mungus posted a cell concept (picture is at the bottom of this post.)

I am thinking of building a reactor off his concept design using clear PVC pipe. This idea will use a separate tube for each electrode so I can be sure the gases do not mix; then only use the pure hydrogen on the fuel cell. As long as the PVC piping is resistant to the NaOH solution, I think it will work. I am not sure of that though. I have not found information that answers this question yet.

So there will be another delay until I build a concept reactor. No sense ruining the fuel cell now just to get some data and pretend like I am accomplishing something.

Thanks for your interest.

Nonetheless your effort is apreciated so we don't make a mistake,
Is probably to early for this question but do you have and idea if the battery will use less energy to regenerate the reaction than to recharge itself?
