Hi Bob,

You wrote:
Let it cook a few days straight to clean out the cells.

This explanation is not clear for me.Coul you interpret me clearer?
Next,My electrolyser today produce 1.5L/min with 12Amps and 14V,but after that curent rise up and stopped between 15 and 16 amps.I donnt need more than 12 AMPS.Can I solve that problem with more diluted concentration.Now I am using 28% KOH

I think he wants ya to empty out the electrolyte fill with distilled water and hook it up a few days to clean off the plates and emty out again,then rinse it out and the use fresh electrolyte

What about CLR cleaner?

[chrissnz]

By memory CLR is phosphoric acid so if there was any lye residue it would react to form a salt which would be likely to cause pitting.

Bob...

I totally get what you're saying here. It makes perfect sense. No contamination. Now, I've been at this site for quite a long time now and I don't remember this being mentioned.

When you put the cells together, you sand a cross-hatch in the plates with course sand paper. Now, what would be the best way to clean the plates after doing that? I mean, a dry cloth, sure...but there's always that extremely fine metal grit (and sand grit) that gets in the metal, and needs something to clean it out with (usually some sort of chemical). Now, I believe I used either naptha, or some sort of fuel like that (which may be my problem) since I'm getting foaming, and yellow at the top. Also, my first unit was not the cleanest at all. Now, I am really interesting in cleaning it and the rest before I put them all together.

What are your suggestions on the best way to have everything perfectly clean? This includes cleaning my PVC, and stainless.

Any other suggestions as well would be great. I'm trying to get around "cooking" all of the units I might make. I will definitely do it to these units, but I am trying to prevent the need

Thanks!

Does electrolyte foaming cause high concentration of electrolyte?

Bob,
The silicone I use in making my units gives off acetic acid while it cures, which I bet is why I haven't been able to run more than maybe 5 amps through them. Will this condition last forever or will it improve?

Hi,

Today I put 20%KOH(before was 28%),but curent again raise to 15-16 AMPS.
With 15.5 AMPS and 14.2V I made 2L/min.
You Bob suggest me to add one cell more,but I would like to drop curent down to produce 1L/min with this electrolyser.Does have some way,maybe drop to 15%

That means PWM controller.I didn't found controller over 10A.

Hi Bob,

I am aware of that kind of battery chargers, and also have one of these smart battery chargers. But how can I connect them between the car battery and the electrolyser.
