1.What kind of reonance you are using to improve efficiency from 15L/min to 75L/min(PWM3E or some other resonance).
2. can I use resonance for "Chris " design(maybe 60-70 cell)
3.does PWM3E works for one cell electrolyser?
Thanks

The welding gas generator in the project pages was constructed with 71 series 6" X 6" plates. So yes, it is large, but not any larger than a large car battery. The plate spacing is 1/8", so it does not take a lot of room for 70 cells of that size. The DC production rate of 15-16 LPM is just that, production at DC. With the resonance drive, that unit can produce 75 LPM without a problem. Just look up posts and info on the PWM3E, or the HexController (not yet released) which is the next generation unit that gives more precise production control.
The welding gas generator sized units run from 120 VAC rectified/filtered to be about 156 VDC. It can also be powered from an inverter that takes automotive 13.8 VDC and steps it up to about 160 VDC. Normally that output is fed to an H-bridge to output simulated 60 Hz AC. By bypassing the H bridge, you have a source of about 160 VDC.
However, you will not see me post anything about installing such a unit in a car. That is not my goal, nor my driving force. The reason you do not see me talk about more is I do not go into details of everything I do, on a public forum. All I will share is my research as related to boosters and welding gas generators. I've experienced first hand what can happen when one dares to go against the status quo, and I do not care to experience it again. I leave that to others to experiment with and talk about.
I agree, the price of 316 is getting so outragious. 304 will work at reduced efficiency. You can buy or build a DC to DC converter (buck converter) to provide whatever operational voltage/current you desire from an automotive source. There are some that get some pretty darned good efficiencies to boot as well.

Do you all really think that calculations based on BTU or comparing to gasoline is really going to get you anywhere. This is the EXACT SAME process the naysayers have been using for ages to keep others from trying. Just build it and do it, it's just that simple. Hydroxy gas is not gasoline, and it is not H2. It has its own unique properties and energy characteristics, that are not found in the texts. Tank hydrogen has a predictable energy pattern, since it is the lowest energy form of hydrogen there is. WE ARE NOT DEALING WITH TANK HYDROGEN
Jeesh, give it up already and just get on with the experiments.
Oh, and the 2 LPM "barrier" mentioned? Since when? I have produced flow rates too high to measure with what equipment I have, and have not consumed kilowatts to do it. 15 to 16 LPM just with straight DC in a single welder sized cell stack unit running on an inverter.

I'm Not sure if the numerical figures above take this into account.

I don't think its unrealistic to create that much on demand.

Visualizing this, is pretty close to a 2.5ft (lwh) cube of air every minute. I guess its not that bad.
My first goal will have to be 6cfm of hydroxy then.
