Plate cell construction (setup without use of chemicals)

Tonight, i will run test with lower voltage. 5 volts.
Then i can make my mind up on the size of the platecell.

Today i ran a 3 plate setup.
To test the option of a neutral plate and what would happen.

Results:
1 neutral on 12Vdc with tapwater works.
1 neutral on 5Vdc with tapwater does not work at all.

12Vdc with 1 neutral plate drops the amps from 1.53 till 0.6 amps.

Conclusion: with lower volts, you will get a higher efficiency, but you have to use more plates and greater plates.
Plate size must be a factor 3 till 4 bigger before you get the same amp draw.

If you wanna see a video of this 3 plate setup, just go to:



gap space is 0.6mm

Hi,

The following parameters will be used on my next WFC.

1. Voltage: 12VDC
2. Amps max: 32A
3. Watertype: Tapwater
4. Chemicals: NON
5. Gap space between plates: 0.022 inche
6. Plate height: 5 inches
7. Plate length: 8 inches
8. Neutral plates: 1

Aloha,
Yes, those plates were in parallel.

Running tap water and straight DC is, in some opinions, not a practical why to formulate testing.
Aside from the chlorine, your tap water likely contains dissolved solids which affect acidity. Like adding a weak electrolite.
Have you done a PH test on the water?
Is it neutral PH?
Is it consistant day by day?
Do you live in an area where old pipes may be present- which could leach iron, lead, etc?
It would be best to use distilled water, or at least filtered water.

Bill,

I am aware of the fact that my tapwater is pretty constant and is holding some stuff in it.
The fact is that i want to drive on tapwater. I dont wanna buy destilled and KOH.
Destilled is asking for chemicals, otherwise it is doing nothing.

Aloha,
I live in an agricultural area. The result is fertilizers leach into the water. My water has a slightly acidic PH.
Also my home is almost 70 years old. Even though I have replaced all of the plumbing, I bet there are a lot of old pipes here, and I live at the bottom of the sub-division. As a result, I may get contaminates from my neighbors too. I don't drink tap water here, even though it tastes good and comes from a beautiful spring.
The point is, when I put this tap water into a cell, it really reacts. Even if you have really super clean tap water, it's a good idea not to recommend it. Most communities sell filtered water cheaply. At least do a PH test. A dissolved solids tester can be had for a reasonable price. If your PH is not neutral, then your not much different than the guy using a slight amount of lye, etc. in distilled water.

You are right, bill.
I will run a ph test.
Do you have numbers on how much ph water may have?

Aloha,
Thanks for the reply.
Neutral PH is technically 7.0. Anything between 6.5 and 7.5 could be neutral.
If your water, even neutral, develops a scum on top, it is contaminated.
Filtered water will get dirty too, buts it's a good option, usually consistent. A good standard. When you duplicate Stan- then water choice may not be as critical.
