Plate spacing becomes a critical factor for miniaturization. If the plate spacing is too close, then effective plate surface area becomes blocked with bubbles. Sonic or ultrasonic vibration may help clear the plates faster, but at the expense of additional hardware and energy cost
Effective plate area divided by current flow determines current density. Current density determines power efficiency. In electrolysis, while X amount of current will create X amount of hydroxy gas, the voltage it takes to push that amount of current increases as current density increases. Increased voltage increases losses to resistive heating. Power wasted in heating is power not used to create hydroxy gas.
Faraday efficiency is where most experimenters concentrate their efforts, and I have been told numerous times that I waste my time on improving power efficiency. When it comes down to the bottom line however, it is power efficiency that determines how much energy is required to power a particular system at a particular output. It may not be critical for a grid powered welding gas generator, but if you want to power your system from an independent power source such as a generator or automotive electrical system, power efficiency becomes quite critical.

Not sure what you meant by blank minature units?
What do you mean by blank?

Seriously, the research everyone is doing here interest me..
I've said previously that the electrolyser have the greatest capability of improvement .. I just don't see the improvement yet .. .
It is unclear what have been done or not ..
What would be cool, is better organisation .. A forum is good, but have it's problems.. I see you are trying to get over the problems with a project page.. which is good.. but I think that the forum about Electrolysis could contain more threads (subjects) .. A special page for frequencies, power supplies, water information, steam, chemical reactions, materials, suppliers etc. .
Well if I was not that lazy I could do it on my web page, but I tend to forget about maintenance . .
Anyways ..
I also have this suggestion, why not making miniature units with tight spacing ...

Loster, noone here is disrespecting your NaOH/Al research, so please don't go around disrespecting others.

Well, 1.5 LPM is crap . .
And be careful when asking for Specs here because you'll be blasted from all around and you will not understand what is going on ... ;]
Here is like a church, they want you to believe, but don't ask for the truth..
Just try the chemical version NaOH + AL .. It's consuming a bit of AL (- REALLY not that much!! -) A bit of NaOH and a bit of water . .
I can't say for sure, but with 1 pound of AL you should be good for a bunch of H2 .. .
Can't say for LPM .. Varies between 0 and Infinite depending on how many units you'll put in parrallel ...
It's tough to build a tranportable unit, that's why I'm orienting my design for household electricity ..
Just use recycled coke cans and you have a working H2 Generator based on old coke cans .. Collect the Alumina and regenerate some AL . .
And if you want to be an AssHole, with plug your electrolyzer to the generated eletricity you made with the chemicalyzer and generate that little 1.5 LPM and run your fridge, computer, lights and heating .... 8]]]]]]
