How to build a cheap and durable electrolytic cell


Hi

Does anyone know how to build a cheap and durable electrolytic cell (under USD 10 ) that can be used for electrolysis of different chemicals. Thanks in advance!

Woelen has a great description on their web site.

Obviously if you went with platinum electrodes your $10 would be blown out of the water, but you can cheaply source carbon rods from zinc batteries or gouging rods.
For a power source you can use one from an old PC, they work well and if you keep your eyes open you can get them quite cheap.

There are also heaps of threads on this topic on SM.

A mug? There's not much more to it. Then there's the electrodes, and what they need to be made of is entirely dependent on what you're wanting to achieve. Stainless steel works for a lot of things, especially in alkaline conditions.

10 USD uhhh well just get a plastic bottle or a mug and a popsicle stick and drill 2 holes and for power supply if you have an old PC power supply its basically free otherwise maybe use a bunch of D cell batteries for 4.5v in series parallel configuation.

It really depends on what you want to do. When I started in the hobby, I used plastic containers, copper and carbon electrodes. For the power supply, I like to use wall warts, you can get them for free in the electronics dumpster at your local recycling center/supermarket

A neat material is flower pots, they can make nice porous separators between two electrolytes

Do you get your carbon electrodes from batteries?

I have tried carbon rods from zinc 6 V lantern batteries and carbon gouging rods. The gouging rods performed better (sloughed less carbon) and are more easily made usable as an electrode, as you don't have to extract them from the battery packaging and mess of magnesium oxide, just a thin layer of copper.

I wouldn't even bother with electrodes sourced from batteries. They tend to just flake apart, even with super low currents. Just get some gouging rods and dissolve away the copper. They perform quite well and last a long time.



Nuclear physics is neat. It's a shame it's so regulated...

Now that I think about it, that's probably a good thing. Still annoying though.
