1 anode for oxygen 2 cathodes for hydrogen?
I have read in several places that a good electrolyzer should have 1 anode (Positive) for the oxygen, and 2 cathodes (negative) for the hydrogen.

The logic for this is simply that H2O has two hydrogen atoms and one oxygen. Basically, should the surface area of the negative be twice that of the positive? What do you guys think? Does it really matter?

Thanks, Gomelesose

Thats what I am playing with now I put in 2 negative and 1 positive all thread ss rods it is working better as far as I can see.I will test this for a few days (5 or 6) and add 2 more negative all thread ss rods to see if 4 to 1 works better.

Then you'll have to test it with one negative and 2 positive to see how your gas output/mileage is affected (just swap your wiring around).

I found that the negative side corrodes fastest.

I do specifically remember Bob Boyce stating that it was a myth that we need 2 Cathode electrodes. Either way he said it didn't matter. But, let us know what your findings are.
