Linnard?s hydrogen on demand system without electricity !

[ResinRat2]

Hi Chris,

So far I've kept it at 0.830 volts for several hours. It looks like the zinc is replating, but I think it's on the cusp. It almost looks like the oxygen is not coming off enough and the zinc is replating in an almost hybrid of zincate and zinc. I think I need to bump up the regeneration voltage a bit more, but I know for sure the zinc will be plating heavily on the tungsten carbide hydrogen producing electrode then.

So your idea of using a resistor between the zinc and the tungsten/carbide electrode (hydrogen producing) would help to prevent the plating, but I don't want to stop the hydrogen reaction.

My electronics kit has a series of resistors that span from 100 ohms to 470K. I need some help in choosing what resistor to slip between the tungsten carbide and zinc electrodes to prevent the plating of the zinc. How do I do this?
I need a bit of advice here.

Thanks for your help in advance.

Pictures of a zincated electrode and the electrode in my present cell.

See how the zincated electrode is bumpy and irregular. A zinc plated electrode would be smooth with some small feathery metal covering the outside of the electrode. The electrode in my present cell shows almost a hybrid between the two. That is why I can't lower the regeneration voltage. I need to bump it up a bit.

Present electrode. Kind of a hybrid between zincated and not zincated.

Hi Chris,

The smallest resistor I have is 100 ohms, and when I placed this between the zinc and tungsten/carbide electrode the reaction virtually stopped. So what I have won't work.

I stopped the reaction and visually examined the tungsten/carbide electrode and was pleasantly surprised to see no zinc had plated on it. So I started the reaction back up and increased the regeneration voltage to 0.85 - 0.90 volts. I still don't see much oxygen coming off the zinc electrode though. I am thinking that the hydroxide is being consumed.

I will let this run until tommorrow, then I will start a new cell with fresh solution and crank it to 0.9 volts right at the start, maintaining this voltage throughout the experiment. I want to see if I can get the oxygen to come off freely, just like the hydrogen.

Hi Dave,

You need to measure the resistance from one end of the zinc electrode to the other end and record it, then compare it to the tungsten electrode. Basically the easiest path is the one that will be plated. if you can make the tungsten the least preferable route then you should be ok.

To reduce the resistance... place resistors in parallel. Two 100ohm resistors in parallel equal 1 50ohm resistor.

I will make my measurements tomorrow and let you know what resistance I am using.
