Hi everyone,
I'm extremely new to this forum and HHO in general. I’m interested in building a dry cell.

Would a 12”x12” with 11”x11” exposed plate surface be a better than two cell’s that are 6”x6” with 5”x5” surface exposed?

The reason I ask is that I read that there is a fluid temperature at which you have optimal hydrogen output.

Also is a large cell inefficient at low amperage?

I have a 95' Honda Civic DX 1.5L OBDI which I would like to install the cell into and I would like to run the cell at no more than 20A.

Any help and suggestions are appreciated thanks.
