Higher efficiency electrolyzer

[dcjuicer]

I placed this comment in a reply on another topic and thought it would be helpfull to all. I am not stating this from any results I have attained but from common-sense. If you made shallower and wider units, I believe your efficiency should be higher. If you made one that had a vacuum in the chamber you would get even better efficiency. (easier said than done I'm sure) Water is about 8 lbs. per gallon, and at the bottom of a one gallon container, a bubble will have 8 lbs. of force compressing it, therefore making it harder to form. If the plates only had a few ounces of water weight pressing against it or a negative pressure, you would get much more efficiency.

The pressure at the bottom of a small container like that is very low. It is water coloum height that determines the pressure, not the weight of the entire water volume. For fresh water it takes about 33 feet of water coloum to equal 1 atmoshere, or about 14 PSI. So a little container like that would have only a small fraction of 1 PSI.

When you put a container of water or electrolyte under vacuum and perform electrolysis, the hydroxy gas output is not increased. The pressure is lower, so the gas expands to take up more volume, but that is all. You will get more water vapor production as well due to lowered partial pressure, which is counterproductive to gas purity. It will not however increase the amount of hydrogen and oxygen split from the water.
