Neutral plates

[dandi]

I know that neutral plates are used to lower the voltage between the + and -. If you have between + and - 12V and 5 neutral plates equally spaced between, than you will have a 2V between 2 neighbour plates. This helps to reduce the heating problem.

But what about the type of gas that it is formed?
Every plate will act like a + and - ? and oxygen and H will be formed on bouth sides?

Or is like only on the main + will have more oxygen and as we go further on the - side will get more hidrogen?

The neutral plates become bi-polar meaning you have - on one side and + on the other. So, you have Hydrogen on one side and Oxygen on the other. If spacing is correct then you should have the same amount of H and O coming off all the plates.
