Uhmm….and how can I utalize this experiment to my advantage? I see no gain in this. But much potential

you just need to …
you just need to crack the pencil sideways. You can take a hammer and nail and just tap it on one end until it cracks, then keep going down until you’ve cracked it most of the way down, rip it apart, and then pull the lead out.

heat it using a low …
heat it using a low voltage but pretty high current source.
It should melt the glue and come out in one piece

Warning! This operation si dangerous, and by doing this one might electrocute, set oneself or others on fire, and so on with the bla-bla-bla. u get the point.

An electrolyser it …
An electrolyser it is, but not a pure water one

The electrolyte is water but the “tap” kind of. So, naturally, will contain some impurities and will not have a perfectly neutral Ph.

I don’t see any proton exchange membrane in that jar. Where’s the similarity?

Plain simple tap water electrolysis…

carbon or graphite …
carbon or graphite rods will not react chemically with water, oxygen nor the hydrogen produced in there.
It does not act like a catalyst, just maintains a good conductivity and does not develop an oxide layer as in the case of metallic rods/electrodes.

Try using two graphite concentric cylinders for greater surface area
Space and center them with glass rods or ceramic spacers.

Greets!

What a cool little demo, thanks for sharing!

so the volts in the water will keep rising if the solar panel is still connected?

Why do you need the …
Why do you need the carbon rods??
wouldn’t it still work if you simple put the wires in the water?

Dude. You are …
Dude. You are splitting water with a current. This is not how a hydrogen fuel cell works. Oxidation happens on the anode. Hydrogen (i.e. protons) need to be reduced. Hydrogen is forming at the cathode (+ end).

A fuel cell oxidizes hydrogen along a platinum anode, the resulting protons go through a proton permeable membrane, and reduce with oxygen at the cathode to form water. The information in this video is incorrect.

Now what can we do …
Now what can we do with the hydrogen?
